TS-2000/X
Overview of the Operation
The TS-2000/X basically consists of an all-mode-receiver
incorporating an IF/AF DSP for satellite communication with
an independent FM/AM sub-receiver for the VHF and UHF
bands.

Overview of the operation of the all-mode trans-
ceiver unit (main band side) with an IF/AF DSP
for satellite communication
The receiver unit has an independent front end for each
of the HF, 50MHz, 144MHz, 430MHz and 1.2GHz bands
(some products do not support the 1.2GHz band).  The cir-
cuits following the 10.695MHz IF stage are common to all
the bands.  (Thus, it cannot receive two SSB signals at the
same time.)
The IF frequency of the transmitter unit is shifted from
the IF frequency of the receiver unit by 100kHz to enable
satellite operation (full duplex operation).  The final section is
independent of the HF, 50MHz, 144MHz, 430MHz and
1.2GHz bands.  Consequently, you can select a combination
of bands permitting satellite communication from the HF,
50MHz, 144MHz, 430MHz and 1.2GHz bands.
The transmitter unit and receiver unit on the main band
side operate simultaneously during satellite transmission.
The receiver unit on the sub-band side does not work.  (The
sub-band receiver is not used during satellite operation.)
Two 16-bit DSP ICs are used; one performs IF processing
(main band side) and the other carries out AF processing
(main and sub bands).  Although the DSP IC is a 16-bit unit, it
carries out “double-precision operations” for critical parts of
IF processing to perform 32-bit equivalent processing.  In
addition, the DSP IC uses a 100-MHz high-speed internal
clock.  The conversion from an analog signal to a digital sig-
nal (A/D conversion) is performed with 24 bits at high preci-
sion.
The DSP circuit for IF operates in any mode other than
FM mode for both transmission and reception.  FM modula-
tion, detection and squelch processing are conventional ana-
log processes.  (The processing prior to modulation and af-
ter demodulation in FM is performed by the DSP.)
In the mode in which the IF DSP circuit operates, it car-
ries out modulation and demodulation, digital IF filtering,
digital AGC, and CW waveform processing during transmis-
sion, as in the TS-870. All these functions are operated in all
the bands on the main band side, including satellite opera-
tion.
The AF unit is processed by the DSP in all modes.   The
operating range of the DSP circuit depends on the mode,
but it performs beat cancellation, noise reduction, AF DSP
filtering, etc.

Overview of the operation of the independent
FM/AM sub-receiver unit (sub-band side) for the
VHF and UHF bands
The local oscillator system and IF/AF signal system of the
sub-receiver unit are independent of the main band side.
Therefore, the sub-band receiver can receive signals while
the main band receiver is sending a signal.  (Except when
reception is impossible due to harmonics of the transmit fre-
quency and when the main band and sub-band are on the
same frequency band.)
The sub-band receive signal is branched from the RF unit
on the main band side.  It is, therefore, not necessary to
install a dedicated antenna for sub-band reception.
Transmission can be performed with the sub receive fre-
quency by shifting the “PTT band” to the sub-band side.  It
is made possible by internally using the transmission func-
tion on the main band side.
AF processing is also carried out by the DSP on the sub-
band side and the noise reduction function works.
The sub-band reception function, including display, can
be turned off.
Frequency Configuration (Fig. 1)
This transceiver utilizes double conversion in FM mode
and triple conversion in non-FM modes during transmission.
It utilizes triple conversion in FM mode and quadruple
conversion in non-FM modes during reception.  The fourth
12kHz IF signal is converted from analog to digital and con-
nected to the DSP.
When the carrier point frequency of the signal input from
the antenna is f
IN, the relationship between these signals
when demodulating this signal is expressed by the following
equations:
HF MAIN f
IN = fLO1 – fLO2 – fLO3 + fLO4 – 12kHz
VHF MAIN f
IN = fLO1 – fLO2 – fLO3 + fLO4 – 12kHz
UHF MAIN f
IN = fLO1 + fLO2 + fLO3 – fLO4 + 12kHz
1.2G MAIN f
IN = fLO1 x 2 + fLO2 + fLO3 – fLO4 + 12kHz
Reference Signal Generation Circuit
The 15.6MHz reference frequency fstd for PLL frequency
control is generated by the TCXO (X400).  The signal passes
through a buffer amplifier (Q420) and is used as the refer-
ence signal for the second local oscillator (HFLO2) for HF
band reception and the first local oscillator (SLO1) subband
reception.
The reference signal is doubled by Q412, and the result-
ing 31.2MHz signal is used as the reference signal for DDSs
(IC406, IC407, IC408, IC601, IC602, IC603).
The 31.2MHz signal is supplied to the TX-RX2 unit (X57-
606 A/11) as LO2 for VHF and UHF bands.

When the HF and or 50MHz band is operating in the main
band, the HF REF VCO (Q427) generates 31.17 to 32.834
MHz.  (See Table 1, frequency configuration.)
The output signal from the DDS (IC408) is input to pin 8
of the PLL IC (IC409) for HF REF, divided into 1/16 in IC409
to produce comparison frequency fø 2 of 487 to 513kHz.
The output signal from the VCO (Q427) goes to pin 6 of
PLL IC (IC409), is divided into 1/64 in IC409, and compared
with the signal with comparison frequency fø 2 by a phase
comparator.  The frequency is locked and the HF REF signal
is output.
The output signal from the PLL IC (IC409) for HF REF is
fed to pin 8 of the PLL IC (IC414) for HF LO1 as a reference
frequency, and divided to produce comparison frequency
fø 1 of 975 to 1358kHz.
The HF LO1 VCO (Q459, Q460, Q464) generates 75.955
to 129.185MHz.  The output from this VCO goes to pin 6 of
IC414, is divided into 1/N 1 in IC414, compared with the sig-nal with comparison frequency fø 1 by a phase comparator.
The frequency is locked and the HF LO1 output frequency is
generated.
The DDS (IC408) sweeps output frequency (7.792 to
8.209MHz) in 10Hz steps by equation f
DDS STEP (Hz) =
(10*R 1)/(N 1*4) and in 1Hz steps by equation f
DDS STEP
(Hz) = (1*R 1)/(N 1*4), the HF LO1 covers the  frequencies
of 75.955 to 129.085MHz in 10Hz or 1Hz steps.
One of three VCOs (Q459, Q460, Q464) is selected by
the signal (HF VCO1,HF VCO2,HF VCO3) from the serial-par-
allel IC (IC404).
The output from the VCOs (Q459, Q460, Q464) passes
through a buffer amplifier (Q462), is amplified by Q476, and
passes through a low-pass filter.  The impedance is con-
verted by an attenuator and the signal is output as HFLO1.
The cut-off frequency of the low-pass filter in the output
section is changed by turning Q474 ON/OFF with a VCO se-
lect signal (HF VCO1).

The output signal from the VCO (Q406, Q407) passes
through a buffer amplifier (Q413, Q414), is amplified by the
broad-band amplifier (IC405), and passes through a low-pass
filter.  The impedance is converted by an attenuator and the
signal is output as SLO1.
When the sub band receiver is not operating, Q411 and
Q411 are turned OFF with the BSW1 and BSW2 signals and
sub VCO (Q406, Q407) stops operation.

TS-2000/X
1.2GHz Unit Local Oscillator
The 12LO31 signal (31.2MHz) is quadrupled to 124.8MHz
in Q14 and 15.  This signal is sent to the mixers of the trans-
mitter section (Q1 and Q2) and the mixers of the receiver
section (Q7 and Q8) In the DDS (C4) , 8.323~8.488MHz are output using
12LO31 as the reference signal.  This signal passes through
a filter (CF1 and CF2) and is input to the mixers for reference
PLL signals (Q313 and 314). In Q313 and Q314, the DDS output is mixed with
12LO31 (31.2MHz) and an approximately 39.6MHz signal is
obtained.  This signal passes through a filter and an amplifier
(Q312) and becomes the reference signal of the PLL IC
(IC5). The VCO (Q301) oscillates at 552.253~582.303MHz.
This signal is amplified in Q302 and goes to the PLL IC (IC5)
and Q19. The PLL IC (IC5) divides the reference signal (approxi-
mately 39.6MHz) to 1/72.  The signal from Q302 is divided to
1/N (N=1006~1058).

The two signals are compared in the phase comparator
within the IC and the VCO (Q301) oscillation frequency is
locked. The signal input into Q19 is doubled.  This signal passes
through a filter and an amplifier (Q20) and goes to the send-
ing mixer (D1) and the receiving mixer (Q10).
Table 5 1.2GHz band frequency configuration
Local  Signals
The RXLO3 (11.15MHz) and RCAR (467kHz) for reception
and TCAR (10.583MHz) for transmission are output from
DDSs (RXL03 : IC603, RCAR : IC601, TCAR : IC602). The frequencies of local oscillator output signals (LO1,
LO2, RCAR, TCAR) for each band are shifted by offset (IF
filter setting), RIT, XIT, IF SHIFT as listed in Tables 5 to 11.
