NAME

RFIN2

GND

FUNCTION

Amplifier 2 Input. Incorporates an internal DC-blocking capacitor and is internally matched to 50W.

This input is designed to be connected to a bandpass filter.

Electrical Ground

4

EXTCAP/

ALT_VCC

External Smoothing Capacitor for Internal Supply Voltage or Can Be Used as the External DC Supply

Pin to Eliminate the Need for a Bias-T on Pin 5

5

RFOUT2/VCC

Amplifier 2 Output. Incorporates an internal DC-blocking capacitor and is internally matched to 50W.

DC bias on this pin serves as the power supply through a bias-T.

6

RFIN1

Amplifier 1 Input. Requires external DC-blocking capacitor and matching components.

7

GAIN_SELECT AMP 2 Gain Select. Open is high-gain mode. Short to ground is low-gain mode.

10

RFOUT1

Amplifier 1 Output. Incorporates an internal DC-blocking capacitor and is internally matched to 50W.

This output is designed to drive a bandpass filter.

EP

Exposed Pad

Ground. The exposed pad must be soldered to the circuit board for proper thermal and electrical

performance.
