Product Description
The RF2103P is a medium power linear amplifier IC. The device is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final linear RF amplifier in UHF radio transmitters operating between 450MHz and 1000MHz. 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 network, power supply feed line, and bypass capacitors, and it produces an output power level of 750mW (CW). The device can be used in 3 cell battery applications. The maximum CW output at 3.6V is 175mW. The unit has a total gain of 31dB, depending upon the output matching network.
