Pin Function Description

Interface Schematic

1

RF IN

RF input pin. This pin is DC-coupled and matched to 50Ω at 1880MHz.

PD

RF IN

2

GND1

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.

3

VPD

Power Down for the IC. 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 minimized. 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).

4

RF 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 typi-

cally matched to 50Ω with a shunt bias/matching inductor and series

blocking/matching capacitor. Refer to application schematics.

5

GND2

Ground connection. For best performance, keep traces physically short

and connect immediately to ground plane.
