The HMPA and HHPA lines of millimeter-wave power amplifiers from HXI Millimeter Wave Products have grown with the addition of a dozen new models covering a total frequency range of 17 to 96 GHz. Well-suited for applications in communications systems, radar systems, and test equipment, the amplifiers combine high gain and respectable output power at 1-dB compression with the ease of a single bias supply. The amplifiers are built on proven monolithic-microwave-integrated-circuit (MMIC) device technology, and come in compact housings with coaxial or waveguide connectors.
As an example, model HHPAB2.4-511 operates from 40.0 to 47.5 GHz with 15-dB typical gain and +23-dBm output power at 1-dB compression. It’s equipped with 2.4-mm female coaxial connectors. For a somewhat higher frequency range, the new model HHPAV-510 offers a bandwidth of 50.0 to 66.0 GHz. It features 34-dB typical gain with +14-dBm typical output power at 1-dB compression. It’s supplied with WR-15 waveguide connectors.
Toward the high-frequency upper limits of the amplifier family, model HPAW-530 covers the 4-GHz bandwidth from 92.0 to 96.0 GHz using WR-10 waveguide input and output connectors. It achieves +15-dBm output power at 1-dB compression with 30-dB typical small-signal gain. For improved reliability and ease of use, each amplifier contains an internal voltage regulator and bias sequencing circuitry.
