[SatNews] MITEQ Inc. has introduced a new addition to the company's extensive line of very low noise waveguide LNAs, a new Triple-Balanced Mixer, and a new LNA. The AMFW-3F-12201270-10-15P is a half-height WR-75 integrated LNA designed for harsh environmental and extreme temperature conditions. In addition, it is designed to be extremely small, lightweight and for low power dissipation, ideal for airborne and portable applications. This model offers a noise figure of 1.1 dB maximum at +70°C ambient, 0.9 dB maximum at room temperature and 0.8 dB typical at 12.2 to 12.7 GHz. At -55°C, noise figure is 0.65 dB typical. The AMFW-3F-12201270-10-15P has a gain of 23 dB ±3 dB over the entire operating temperature range, port match of 1.5:1 maximum VSWR. Maximum current draw is less than 100 mA from a single 12V supply. Typical P1dB is +14 dBm and output IP3 is typically +25 dBm. Complete LNA weighs less than 30 grams. This model is also offered in tight gain/phase-matched pairs or lots.

Also now available from MITEQ is a 2-50 GHz Triple-Balanced Mixer. In addition to its ultra-wideband RF and LO capability, the TB0250LW1 also has an ultra-wideband IF response. Applications include a single LO block conversion of the low Ka-bands into an existing common frequency receiver front end. This device performs as an up- or downconverter. The TB0250LW1 meets rugged environmental MIL specs, operates over a -54 to +85°C temperature range and is ideal for rugged Military and Commercial system applications.

MITEQ Inc. has also debuted a new addition to its family of LNAs. The Model AFS4-00101200-18-10P-4 is ultra low noise, lightweight, and has a small profile and footprint. The Kovar housing is a hermetically sealed package. This unit has an ultra low noise figure of 1.8 dB maximum. Input and output port VSWR is a maximum of 2:1. Small-signal gain is 28 dB minimum and P1dB is +10 dBm minimum. The AFS4-00101200-18-10P-4 comes with various options such as various bandwidths, cryogenic models, input limiter, input/output DC block, and bias through output. Operating temperature is -54 to +85°C case.
