Product Description

The RF2114 is a medium to high power linear amplifier

IC. The device is manufactured on an advanced Gallium

Arsenide Heterojunction Bipolar Transistor (HBT) pro-

cess, and has been designed for use as the final linear

RF amplifier in UHF radio transmitters operating between

1MHz and 600MHz. It may also be used as a driver

amplifier in higher power applications. The device is self-

contained with the exception of the output matching net-

work, power supply feed line, and bypass capacitors. The

device can be used in 3-cell battery applications. The

maximum CW output at 3V is 125mW. The unit has a

total gain of 35dB, depending upon the output matching

network.
