Function
Description
Interface Schematic
1GND
Ground connection. Keep traces physically short and connect immediately
to ground plane for best performance.
2GND
Same as pin 1.
3RF IN
RF input pin. This pin is DC coupled and internally matched to a <2:1 VSWR
at 1880MHz.
4PD
Power Down for the IC. VPD = 2.8V +/- 0.1V turns on the Part. VPD<0.9V
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.
See pin 3.
5GND
Same as pin 1.
6RF 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 50
Ω with a shunt bias/matching inductor and
series blocking/matching capacitor. Refer to application/evaluation board
schematics.
