GaAs MMIC Double Balanced Mixer requiring no matching circuitry.

Press Release Summary:

Applicable in point-to-point and point-to multipoint radios, VSAT, sensors and military end use, HMC557A and HMC773A GaAs MMIC Double Balanced Mixer uses optimized balun structures to provide good LO to RF and LO to IF isolation. Applied as up-converter or down-converter from 2.5GHz to 7.0GHz, HMC557A comes in 24-lead, ceramic 4mm x 4mm LCC package. HMC773A comes in 24-lead, ceramic 3mm x 3mm LCC package from 6GHz to 26GHz.

Original Press Release:

Richardson RFPD Introduces Two GaAs MMIC Fundamental Mixers from ADI

General purpose, double balanced mixers with optimized balun structures

Richardson RFPD, Inc. announced today the availability and full design support capabilities for two GaAs MMIC fundamental mixers from Analog Devices, Inc.

The HMC557A is a general-purpose, double balanced mixer in a 24-lead, ceramic 4 mm x 4 mm LCC package that can be used as an up-converter or down-converter from 2.5 GHz to 7.0 GHz and requires no external components or matching circuitry. The HMC557A provides excellent local oscillator (LO) to radio frequency (RF) and LO to intermediate frequency (IF) isolation due to optimized balun structures. It is suitable for fixed wireless, point-to-point and point-to-multipoint radios, test equipment and sensors, and military end use applications.

The HMC773A general-purpose, double balanced mixer, available in a 24-lead, ceramic 3 mm x 3 mm LCC package, can be used as an up-converter or down-converter from 6 GHz to 26 GHz and also requires no external components or matching circuitry. Optimized balun structures result in excellent LO-to-RF and LO-to-IF suppression, and the mixer operates with LO drive levels above +13 dBm. The HMC773A is suitable for point-to-point and point-to multipoint radios and VSAT, test equipment and sensors, and military end use applications.

According to ADI, additional key features of the devices include:
