Product Description
The RF2104 is a medium power amplifier IC. The device
is manufactured on a low cost Silicon process, and has
been designed for use as the final RF amplifier in UHF
radio transmitters operating between 400MHz and
1000MHz. It may also be used as a driver amplifier in
higher power applications. The device is packaged in a
plastic quad-batwing 16-lead package, and is self-con-
tained with the exception of the output matching network,
power supply feed line, and bypass capacitors. It pro-
duces an output power level of up to 500mW (CW) at
3.6V. The device can be used in 3 cell battery applica-
tions. The maximum CW output at 3.6V is +27dBm. The
unit has a total gain of 26dB, depending upon the output
matching network.
