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 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 also available.LNA includes reverse voltage, over current and over temperature protection in addition to full internal regulation. The product has a typical noise temperature of 100K, with a maximum of 120K, and 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 +70°C case.
MITEQ has also added Model DNB2-11.725TR, Multiband Block Converter, to its 1/3 rack family of products. This model is designed for applications where multiple frequency translations are needed between Ku- and L-band.The 1/3 rack platform provides flexible configurations for use in many earth station terminals while only using 1 RU of rack space.
The third MITEQ debut is the Company’s MOS Series of multi-octave wide, low phase noise synthesizers which offer an economical solution for lab and communication test applications. Band coverage is from 100 MHz to 20 GHz. The MOS Series has a standard 1 kHz step size, with optional full-band fast switching available. The field-tested design and low power dissipation proves to demonstrate higher MTBF and higher reliability. These synthesizers are available in either one third-rack mounted chassis with front panel control, or a modular 5” x 8” x 1.25” package with either serial or parallel control.
