Ku band waveguide LNA

19 September 2012 Analogue, Mixed Signal, LSI

The AMFW-6S-12601520-90-WR62 is MITEQ’s newesthigh-performance waveguide LNA for Ku-band. It is weatherproof and features low noise and high dynamic range, operating from 12,65 GHz to 15,2 GHz.

The device includes a pressure-sealed WR62 waveguide input and SMA (F) output. It includes reverse voltage, overcurrent and over­temperature protection in addition to full internal regulation.

The LNA’s aluminium alloy housing is sealed against severe environmental conditions. Its total weight is approximately 270 grams, and dimensions are 53 x 33 x 33 mm.

The AMFW-6S-12601520-90-WR62 has a typical noise temperature of 80K, with a maximum of 90K, and it is capable of a minimum 10 dBm of P1dB across the full band, with an available option of 20 dBm. Noise temperature will typically change with base temperature of the LNA at a rate of 0,28 K/°C.

Output IP3 is 20 dBm minimum, while input VSWR is a maximum of 1,5:1 and output port VSWR is a maximum of 2:1. Small-signal gain is 50 dB typical and flatness is 2,0 dB peak-to-peak with a maximum gain ripple of 0,4 dB/40 MHz within the whole band.

The device’s gain variation with temperature is less than 0,08 dB/°C; over time the gain is stable to less than 0,4 dB/month. Total group delay is constant to less than 1 ns over the full band. Current draw is nominally 200 mA from a single +12 V to 24 V supply; other voltage ranges and alarm options are available, as is an alarm feature. Operating temperature is -40°C to +60°C case.
