Wideband power amplifier and Ka-Band block upconverter from Hittite

Hittite Microwave Corporation has launched the HMC6980, a 10 MHz to 20 GHz power amplifier module that is ideal for EW, ECM, radar, fiber optic and test equipment applications.

The HMC6980 is a GaAs MMIC PHEMT Power Amplifier in a miniature, hermetic module with replaceable SMA connectors which operates between 0.01 GHz and 20 GHz. The amplifier provides 12 dB of gain, up to +36 dBm output IP3 and up to +28 dBm of output power at 1 dB gain compression. Gain flatness is excellent over the entire 2 to 18 GHz frequency band. The wideband amplifier I/Os are internally matched to 50 Ohms and are DC blocked. Integrated voltage regulators allow for flexible biasing of both the negative and positive supply pins, while internal bias sequencing circuitry assures robust operation.

Hittite Microwave Corporation has also introduced a new Ka-Band Block Upconverter with HPA. The HMC7056 features 65 dB of conversion gain. Its dual input IF is 1 to 2 GHz at 0 dBm typical and is upconvertered to 29 to 31 GHz at a linear output power of 37 dBm.

The HMC7056 has internal local oscillators that require a 100 MHz reference and utilize a dual upconversion 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 upconverter and the high power amplifier (HPA) can be sold as separate units. The upconverter provides SMA inputs and a 2.9 mm output connector. The HPA has a 2.9 mm input connector and WR28 waveguide output. The HPA utilizes GaAs MMIC technology. The individual HPA operates at 5 volts and draws 14 amps. The unit is designed for conduction coolind and operates over the -20 °C to +80 °C temperature range.

All connectorized module products are available from stock and can be ordered via the company's e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
