Function Description
Interface Schematic
Power down for the IC. V = 2.8V +/- 0.1V turns on the part.
PD
PD
PD
V
<0.9V turns off the Part. External RF bypassing is required. The
PD
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 V = 2.8V
PD
is 8.5 mA typical and 12 mA Max (@V =2.9 V).
PD
No connection. This pin is typically left unconnected or grounded.

This pin is typically matched to 50Ω with a shunt bias/matching induc-
tor and series blocking/matching capacitor. Refer to application sche-
