SYMBOL
RFout1
DESCRIPTIONS
RF signal output terminal from Wide-Band variable gain
Amplifier. And this terminal is also the voltage supply terminal
of wide-band variable gain amplifier, therefore should be
supplied voltage through the choke coil.

RFin1
Voltage input terminal or gain control circuit.
Ground terminal. No.3 and No.7 pins connected inside IC.
RF signal input terminal to wide-band variable gain amplifier.
RF signal output terminal from driver amplifier. And this
terminal is also the voltage supply terminal of driver amplifier,
therefore should be supplied voltage through the choke coil.
Ground terminal.
