0.005–29.999 MHz

BPF UNIT

The 2nd IF signal from the MIX2 UNIT is filtered by one of 2nd IF filters (for BW=3 kHz, 6 kHz, 15 kHz, 50 kHz or 240 kHz) to remove unwanted signals. The filtered 2nd IF signal is amplified by 2nd IF amplifier, then applied to the 3rd mixer, and mixed with 3rd LO signals from the PLL UNIT to generate 3rd IF signal.

The generated 3rd IF signal is ampliﬁ ed by 3rd IF ampliﬁ er, and passed through the 3rd IF ﬁ lter (BW=50kHz) to remove unwanted signals. The filtered 3rd IF signal is applied to the 4th mixers (D1250 and D1251), and mixed with 4th LO signals from the PLL UNIT to generate 4th IF signal.

The generated 4th IF signal is ampliﬁ ed by 4th IF ampliﬁ ers, then applied to the MAIN UNIT for demodulation.

In WFM mode, the IF signal from the 3rd IF amplifier is ampliﬁ ed by two 3rd IF ampliﬁ ers, and ﬁ ltered by two 3rd IF ﬁ lters (BW=230 kHz), then applied to the IF IC (IC1031) for FM-demodulation. The demodulated AF signals are applied to the MAIN UNIT via AF switch (IC1312).

PLL UNIT

PLL UNIT supplies the LO (Local Oscillator) signals (1st, 2nd, 3rd and 4th), still more the clock signals for DSP circuits. To obtain physical strength for the VCO1, VCO2, DOUBLER, FIL1 and FIL2 BOARDs, these circuits are shielded and isolated perfectly, by being patterned separately on different P.C. boards.

VCO1 BOARD

VCO1 BOARD has tree VCOs ;VCO-A, VCO-B and VCO-C.

VCO-A (Q1301), as an example, is a colpitts-typed oscillator circuit, and its output signal is buffered by Q1302 and output via diode switch. Q1303 controls the power supply for the VCO, and the voltage of LH3V line adjusts the oscillation level for suitable LO signal level.

The buffer-ampliﬁ ed VCO output signals are divided by the divider, and applied to the LO amplifier via attenuator (as a pad). The amplified LO signals are applied to the RF-A UNIT or FIL1 BOARD as the 1st LO signals, via ﬁ lters and ampliﬁ ers.

The VCO-A is mounted on the nearest to VCO1 board to reduce the signal loss. The resonators are employed strip lines which had been used with SMD electric parts. The oscillating frequency ranges are divide into three for wide oscillation frequency coverage.

VCO2 BOARD

VCO2 BOARD provides the 2nd LO signals for receiving the both of VHF and UHF bands, and contains 3 VCOs oscillating 220 MHz, 720 MHz and 837.4 MHz LO signals.

The 220MHz band VCO is a totem pole typed one with bipolar TRs (Q4100 and Q4101). 20MHz, and 837.4MHz band VCOs are employed tank typed resonator with FETs (Q4201 and Q4301) to obtain good C/N capability.

DOUBLER BOARD

1st LO signals for receiving 1GHz and below frequency are doubled by doublers on the BOUBLER BOARD.

IC-R9500 employed doubler which produces 1st LO signals for the receiving 1.8 GHz and above, and improved the IP3 characteristic and sensitivity, and more, destroyed the necessary of the converter circuits.

The doubler circuit is balanced type and composed by bipolar transistors (Q2200, Q2201). The employment of transistors improved lower conversion loss than by diodes, and the same capability of attenuating odd numbered harmonics as by diodes.

FIL1 BOARD

Fil1 board doubles and ﬁ lters the 1st LO signals for recieving VHF and UHF bands. To suppress the directly oscillated frequency (Fosc×1) MHz and harmonics (Fosc×N) MHz, three staged ﬁ lters are used.

FIL2 BOARD

Fil2 board doubles and ﬁ lters 2nd LO signals. By expanding the pass band width of the BPF, the BPF commonly used for the 1st LO signals genarated by 220MHz, 720MHz and

837.4MHz VCOs. MMIC (IC4450) is inserted in front of the ﬁ lter to make up the 1st LO signal level.
