Ka-Band Waveguide LNA
MITEQ Inc. introduces a new addition to its family of waveguide LNAs. The AMFW-8F-17702130-120-23P is a very low noise, high dynamic range Ka-band waveguide front end. Isolator protected at both the WR-42 waveguide input and SMA(F) connector output, the low-noise amplifier is very lightweight and has an extremely small profile and footprint. The aluminum alloy housing is environmentally sealed and comes with a mounting plate. EMI shield and weather-resistant packaging options are available. LNA includes reverse voltage, over current and over temperature protection in addition to full internal regulation.
The AMFW-8F-17702130-120-23P has a typical noise temperature of 100K, with a maximum of 120K, and it is capable of a minimum 23 dBm of P1dB across the full band, 17.7 GHz to 21.3 GHz. Output IP3 is 33 dBm minimum.
Input and output port VSWR is a maximum of 1.25:1 and 1.5:1 respectively. Small-signal gain is 62 dB and flatness is 2 dB peak-to-peak maximum. Maximum ripple is 0.2 dB/40 MHz within the whole band. Gain variation with temperature is less than 0.08 dB/C. 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 400 mA from +10V supply and a –5V supply is also required. Operating temperature is –40 to +70C case.
