The Miteq AFS3-00010300 is a broadband low-noise amplifier spanning 1 MHz to 3 GHz, delivering 28–34 dB gain with noise figures typically 1.2–2.5 dB across its operating band. This military-grade module provides 50 Ohm impedance matching, ±1 to ±1.5 dB gain flatness, and rated output power of 10 dBm with a third-order intercept point of 20 dBm. Input and output VSWR are held to 2.0:1 maximum, ensuring efficient power transfer and minimal reflections in cascaded systems. Operating from a 15 V nominal supply at 100–125 mA typical current draw, the amplifier maintains performance across the extended temperature range of −54 °C to +85 °C. Two SMA female connectors support straightforward integration into RF chains. The AFS3-00010300 combines quasi-lumped element design techniques with 90° hybrid topology to achieve low-noise performance suitable for communications, radar, test equipment, and GPS/GNSS receivers.
