Hittite’s new HMC7056 is a Ka-band block up-converter, with high-power amplifier (HPA), featuring 65 dB of conversion gain.
Its dual input IF is 1 to 2 GHz at 0 dBm typical and is up-convertered to 29 to 31 GHz at a linear output power of 37 dBm.
The device has internal local oscillators that require a 100 MHz reference and utilise a dual up-conversion scheme to ensure no phase inversion and maximum spurious rejection.
Other attributes include digital gain control, thermal monitoring and gain compensation, PA Enable and an output isolator to ensure excellent output VSWR. The unit is designed for conduction cooling and operates over the -20°C to +80°C temperature range.
The up-converter and HPA can be sold as separate units. The up-converter provides SMA inputs and a 2,9 mm output connector, while the HPA has a 2,9 mm input connector and WR28 waveguide output. The HPA utilises GaAs MMIC technology; the individual HPA operates at 5 V and draws 14 A.
