SYMBOL

DESCRIPTIONS

1

RF

out1

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.

2

V

CONT

Voltage input terminal or gain control circuit.

3

GND1

Ground terminal. No.3 and No.7 pins connected inside IC.

4

RF

in1

RF signal input terminal to wide-band variable gain amplifier.

5

RF

out2

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.

6

GND2

Ground terminal.

However GND1 terminal must not be connected to GND2,

please use different through hole to connect ground plane.

(Please see RECOMMENDED PCB DESIGN)

7

GND1

Ground terminal.

8

RF

in2

RF signal input terminal to driver amplifier.
