Low-Noise Amp Boosts 4 To 12 GHz

Among the many amplifiers and other components on display for satellite communications (satcom) and other high-frequency applications at the 2014 IMS Booth No. 325, model AMF-5F-04001200-12-10P from MITEQ is a coaxial low-noise amplifier (LNA) with maximum noise figure of 1.2 dB from 4 to 12 GHz, with typical noise figure of only 1 dB. Supplied with field-replaceable SMA connectors and measuring only 0.89 × 0.64 in., the LNA provides 39-dB gain from 4 to 12 GHz with minimum output power of +10 dBm at 1-dB compression and typical third-order output power (IP3) of +20 dBm. Designed for operating temperatures from -40 to +75°C, the amplifier draws only 250 mA current from a single +15-VDC supply. Available in a hermetic and RoHS version, the amplifier’s aluminum alloy housing provides excellent thermal performance in addition to being very small and light.
