Description
Interface Schematic
1PD
Powerdownfor theIC. 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 min-
imized. 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).
2NC
No connection. This pin is typically left unconnected or grounded.
3RF IN
RF input pin. This pin is DC-coupled and matched to 50
Ω at 1880MHz.
4GND1
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
5GND2
See pin 6.
6GND2
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
7RF OUT
Amplifier Output pin. This pin is an open-collector output. It must be
biased to either VCC or pin 7 through a choke or matching inductor.
This pin is typically matched to 50
Ω with a shunt bias/matching induc-
tor and series blocking/matching capacitor. Refer to application sche-
matics.
