IN 2

UHF RF input terminal. Input type is 24

balance input. In the case of

unbalance input, grounding of either

pin 13 or 14 with capacitor is

13

required, while input to the other pin.

15 PUHF

Band change drive terminal. Output 24

configuration is PNP open collector.

When band selection bit PUHF is set

"1", current is output.
