Pin Function Description

Interface Schematic

1

RF IN

RF input pin. This pin is DC coupled and matched to 50Ω at 836 MHz.

To Bias

Circuit

RF IN

RF OUT

2

GND1

Ground connection. Keep traces physically short and connect immediately

to ground plane for best performance.

3

VPD

For low noise amplifier applications, this pin is used to control the bias cur-

PD

rent. See plots for bias current settings. An external resistor (R1) can be

used to set the bias current for any VPD voltage.

For driver amplifier applications, this is the Power Down pin for the IC.

VPD=2.8V +/- 0.1V is required for proper operation. 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 2.0mA typical and 3.0mA 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. Keep traces physically short and connect immediately

to ground plane for best performance.
