GaAs MMIC upconverter for radar, electronic warfare, and electronic intelligence applications introduced by Hittite Microwave

CHELMSFORD, Mass., 9 May 2010. Hittite Microwave Corp. in Chelmsford, Mass., is introducing the HMC711LC5 surface-mount gallium arsenide monolithic microwave integrated circuit (GaAs MMIC) sub-harmonic upconverter for military radar, electronic warfare, and electronic intelligence applications from 17.7 to 23.6 GHz.

The HMC711LC5 delivers a signal conversion gain of 15 dB and IF bandwidth of DC to 3.5 GHz, and uses a double-balanced mixer driven by an active x2 multiplier and followed by a high linearity amplifier.

The RF and microwave device also is for point-to-point radio, satellite communications, test and measurement, and sensors applications. This upconverter accepts LO input frequencies from 9.5 to 13.6 GHz, and LO power levels as low as 0 dBm, allowing it to be driven directly from a synthesizer output.

The HMC711LC5 also exhibits +28 dBm output IP3 and +17 dBm output P1dB, and operates from one 5-volt power supply. This high linearity converter is a much smaller alternative to hybrid style subharmonic upconverter assemblies and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.

The HMC711LC5 is housed in a leadless RoHS compliant QFN 5-by-5-millimeter SMT ceramic package, and is specified for operation from -40 to 85 degrees Celsius. For more information contact Hittite Microwave online at www.hittite.com.
