HITTITE Microwave Corporation, represented by ASD Technology in Australia, has released two SMT GaAs MMIC I/Q mixers and an SMT GaAs MMIC double-balanced mixer for VSAT, microwave radio, test equipment and sensor applications from 4GHz to 16GHz.
For applications where a surface mount package is required, the HMC527 and HMC528 are available in RoHS-compliant, 4mm x 4mm leadless SMT packages. The HMC527LC4 and the HMC528LC4 GaAs MMIC I/Q mixers provide RF/LO coverage from 8.5GHz to 16GHz, with Input IP3 up to +28dBm and IF bandwidth as wide as dc to 3.5GHz. Image rejection and LO to RF isolation are up to 40dB and 50dB respectively.
The SMT I/Q MMIC mixers offer significantly reduced PCB area, more consistent performance, and excellent amplitude and phase balance compared to a discrete implementation.
The HMC129LC4 is a 4GHz to 8GHz GaAs MMIC double-balanced mixer which exhibits 7dB conversion loss and LO to RF and LO to IF isolations of up to 40dB. This passive mixer requires no external components, operates over a wide LO drive input of +9dBm to +15dBm, and is suitable for both upconverter and downconverter applications in VSAT, fixed wireless and microwave radio. The HMC129LC4 is housed in a lead-free and RoHS-compliant 4mm x 4mm SMT package.
Each of these mixers is fabricated on a mature, reliable and production-qualified, high-volume GaAs MESFET process.
