RF Circuit
RF Transmission
A digital audio signal and control signal  from LAN is received by DVF99 (IC100) in a cell station.
Then data goes to RFIC (IC501) through SPI and TDM signal, and it's modulated to 1.9 GHz RF signal. The RF signal is ampli-
fied and fed to a selected antenna by antenna diversity.
RF Reception
As for a cell station, RF signal is received in two antennas.
RFIC(IC501) of cell station compares RF signal levels from portable station and selects the antenna to be used.
RX signal in the selected antenna is amplified and down-converted to 864 kHz IF signal, then demodulated to digital data.
Control signal is output to IC100 on SPI signal, and digital audio signal is output to IC100 on TDM signal.
DVF99 (IC100) receives these data and outputs it to LAN.
4.9.
LED Circuit
D101(Green LED) and D102(Red LED), D104(Blue LED) are controlled by IC100(DVF99).
Q104 is used for constant current circuit.
