Special Frequency
GaAsFET Preamplifiers

For over fifteen years, Advanced Receiver Research has produced low noise figure Gallium Arsenide amplifiers for a wide variety of frequencies and applications. Over these years we have assembled quite a “cookbook” that allows us to handle orders for these “special” frequency ranges with the same quick delivery as standard off the shelf units. We do not charge a premium for this service - custom frequency preamplifiers cost no more than our standard units! Listed below are some of the more popular “special” frequency amplifiers that we have built. If you don’t see exactly what you need please call as chances are good we can supply you with a custom preamplifier.
