The RF2362 is a low noise CDMA/TDMA PA driver ampli-
fier with a very high dynamic range designed for transmit
digital PCS applications at 1880MHz. The device func-
tions as an outstanding PA driver amplifier in the transmit
chain of digital subscriber units where low transmit noise
power is a concern. The IC includes a power down fea-
ture that can be used to completely turn off the device.
The IC is featured in a standard SOT 5-lead plastic pack-
age.

V
<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 V = 2.8V

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