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.
