Function
Description
Interface Schematic
1GND
Ground connection. Keep traces physically short and connect immedi-
ately 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 typ-
ical.
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 typically externally matched to 50
Ω with a shunt bias/match-
ing inductor and series blocking/matching capacitor. Refer to applica-
tion/evaluation board schematics.
