Function and Explanation
Non Connection pin.
This pin should be opened.
Automatic gain control pin.
Ground pins of differential amplifier.
Power supply pin of AGC amplifier
block.
Power supply pin of differential
amplifier and output block.
Ground pins of differential amplifier.
Bypass pin of regulator block.
Signal output pins.
This pins feature low-impedance
because of its emitter-follower output
port.
The pin that is not used should be
grounded through 50 ohm resistor.
