The AHP series high power amplifiers are discrete and/or MMIC PHEMT devices based amplifiers that operate at the frequency range between 18 to 98 GHz for high output power applications. The amplifiers are offered in two categories, namely, standard and custom built. The custom built amplifiers are offered in various RF interfaces, including standard waveguide or coax connectors, for convenient system integration. The optional input and output integrated isolators are available to further improve the port return loss.
