Input signal common for limiting amplifier.
Output of first stage of IF amplifier. Normally connected through 10.7 MHz
filter to Pin 12 (LIMIN).
Input to first stage of IF amplifier.
Local VCC connection for IF amp/limiter stages.
10.7 MHz IF Output. Normally connected through 10.7 MHz filter to IF
amplifier input (Pin 15).
Local ground for LNA.
Substrate ground connection.
LNA Input. Normally driven single-ended from 50 Ω source impedance.
VCC for LNA.
Substrate ground connection.
10.7 MHz limiter output.
Local ground for PA stage emitter. Degeneration may be added.
Transmitted RF output signal at 0 dBm level.
Local VCC connection for TX stages.
Logic “1” turns on power to transmit mixer, buffers, and PA stages.
Prescaler Modulus control (HIGH = divide-by-64; LOW = divide-by-65).
