Microwave mixers are all RoHS compliant

Hittite Microwave Corp has two new SMT GaAs MMIC I/Q mixers and a new SMT GaAs MMIC double balanced mixer for Vsat, microwave radio, test equipment and sensor applications from 4 to 16GHz.

Hittite Microwave Corp has two new SMT GaAs MMIC I/Q mixers and a new SMT GaAs MMIC double balanced mixer for Vsat, microwave radio, test equipment and sensor applications from 4 to 16GHz.

For applications where a surface mount package is required, the popular HMC527 and HMC528 are now available in RoHS compliant, 4 x 4mm leadless SMT packages.

The HMC527LC4 and the HMC528LC4 GaAs MMIC I/Q mixers provide RF/LO coverage from 8.5 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 outstanding at up to 40 and 50dB, respectively.

These SMT I/Q MMIC mixers offer significantly reduced PCB area, more consistent performance, and excellent amplitude and phase balance compared with a discrete implementation.

The HMC129LC4 is a 4-8GHz 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 +9 to +15dBm, and is ideal for both up-convertor and down-convertor applications in Vsat, fixed wireless and microwave radio.

The HMC129LC4 is housed in a "Pb free" and RoHS compliant 4 x 4mm SMT package.

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

Samples and evaluation PC boards are available from stock and can be ordered from MRC Components.
