Pin Function Description

Interface Schematic

1

GND

Ground connection. Keep traces physically short and connect immediately

to ground plane for best performance.

2

GND

Same as pin 1.

3

RF IN

RF input pin. This pin is DC coupled and internally matched to a <2:1 VSWR

at 1880MHz.

PD

RF IN

4

PD

Power Down for the IC. VPD = 2.8V +/- 0.1V turns on the Part. VPD<0.9V See pin 3.

turns off the Part. Lower threshold for device operation is approximately

1.2V. 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 for this pin for VPD = 2.8V is 8mA typical.

5

GND

Same as pin 1.

6

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

series blocking/matching capacitor. Refer to application/evaluation board

schematics.
