Function

Description

Interface Schematic

1RF IN

RF input pin. This pin is DC-coupled and matched to 50

Ω at 1880MHz.

2GND1

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.

VPD

PowerDownfor theIC. VPD = 2.8V +/- 0.1V turns on the part.

VPD<0.9V turns off the part. External RF bypassing is required. The

trace length between the pin and the bypass capacitors should be min-

imized. The ground side of the bypass capacitors should connect

immediately to ground plane. Nominal current required for VPD =2.8V

is 8.5 mA typical and 12 mA Max (@ VPD =2.9 V).

4RF OUT

Amplifier Output pin. This pin is an open-collector output. It must be

biased to either VCC or pin 4 through a choke or matching inductor.

This pin is typically matched to 50

Ω with a shunt bias/matching induc-

tor and series blocking/matching capacitor. Refer to application sche-

matics.

5GND2

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.
