Microwave mixers

Hittite Microwave has released seven GaAs MMIC I/Q mixers targeted to VSAT, microwave radio, test equipment, sensor and military applications from 6 to 23.6 GHz.

The HMC526, HMC527 and HMC528 offer IF bandwidth of DC to 3.5 GHz, conversion loss of 7.5 dB and input IP3 of +30 dBm.

As a result of their monolithic construction, the devices provide LO to RF isolation of up to 50 dB, and image rejection of 40 dB, making them suitable for microwave radio and sensor applications from 6-16 GHz.

For applications where a surface-mount package is preferred, the HMC521, HMC523, HMC525 and HMC526 are available in RoHS compliant, leadless 4x4 mm SMT packages. The HMC521LC4, HMC523LC4, HMC525LC4 and HMC526LC4 GaAs MMIC I/Q mixers provide RF/LO coverage from 4 to 23.6 GHz with DC-3.5 GHz IF bandwidth, and input IP3 of +28 dBm.

Image rejection and LO to RF isolation are at 40 dB and 50 dB, while each of these mixers can be configured for either image reject or single sideband upconverter applications.

Each mixer is fabricated on a mature, reliable and production qualified high volume GaAs MESFET process.
