MITEQ Weatherproof Ka Band LNA
|MITEQ has added model AMFW-7F-17702130-120-23P-WP to its family of high-performance waveguide LNAs. The Model AMFW-7F-17702130-120-23P-WP is a very low noise, high dynamic range weatherproof Ka-band front end, operating 17.7 to 21.3 GHz.
With isolator protected and pressure sealed WR-42 waveguide input and K(F) connector output, in addition to being lightweight, this low-noise amplifier has a small profile and footprint. The aluminum alloy housing is sealed against most severe environmental conditions and also fully EMI shielded.
This LNA includes reverse voltage, over current and over temperature protection in addition to full internal regulation. Total weight is approximately 800 grams, and dimensions are 156mm x 70mm x 51mm. The AMFW-7F-17702130-120-23P-WP has a minimum gain of 60 dB, flat to within +/-1 dB, and maximum noise temperature of 120 K and is capable of a minimum of 23 dBm P1dB across the full band. Noise temperature will typically change with base temperature of the LNA at a rate of 0.28 K/degC. Output IP3 is 30 dBm minimum. Input and output port VSWR is a maximum of 1.25:1 and 1.5:1 respectively. Gain is stable to less than 0.4 dB/month. Total group delay is constant to less than 1 nsec over the full band. Current draw is nominally 700 mA from a single +12V to +24V supply. Other voltage ranges and alarm options are available. Operating temperature is -40 to +60 degC (case).
