A line of low-noise-amplifier (LNA) modules has been developed for applications through 18 GHz. Well suited for test, aerospace, and defense systems, the rugged modules meet MIL-STD-883 environmental requirements with noise figures as low as 1.8 dB and output power levels as high as +20 dBm. As an example, model NEL-0618T620-5HM operates from 6 t o18 GHz with a 4-dB noise figure, at least +20 dBm output power at 1-dB compression, and 28 dB gain that is flat within +/-2 dB across the 12-GHz bandwidth. The temperature-compensated LNA module operates from a single +12-VDC supply and draws a maximum of 490 mA current. Another example is model NEL-0102N305-1MH which features a 2-dB noise figure from 0.5 to 2.0 GHz with +5 dBm output power at 1-dB compression and at least 28 dB gain that is flat within +/-0.5 dB. It draws 150 mA or less from a single +12-VDC supply. The amplifiers are designed for operating temperatures from -54 to +85C.
