Product Description
The RF2367 is a low noise CDMA/TDMA/GSM PA driver amplifier with a very high
dynamic range designed for transmit digital PCS applications with frequency ranges
between 1700MHz and 2000MHz. The device functions 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 feature that can be used to
completely turn off the device. The RF2367 is featured in a standard SOT23-6 plastic package.

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.
TO OUTPUT
STAGE
See pin 3.
Same as pin 1.
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 with a shunt bias/matching inductor and
series blocking/matching capacitor. Refer to application/evaluation board
schematics.
