HMC553

HMC553 v02.1007 GaAs MMIC FUNDAMENTAL MIXER, 7 - 14 GHz Features High LO/RF Isolation: 48 dB Passive Double Balanced Topology Low Conversion Loss: 7 dB Wide IF Bandwidth: DC - 5 GHz Robust 1,000V ESD, Class 1C Typical Applications The HMC553 is ideal for: • Microwave Radio • Military & Space • Communications, Radar & EW 4 MIXERS - DOUBLE-BALANCED - CHIP Functional Diagram Small Size: 0.83 x 1.12 x 0.1 mm General Description The HMC553 is a passive double balanced mixer that can be used as an upconverter or downconverter between 7 and 14 GHz. The miniature monolithic mixer is fabricated in a GaAs MESFET process, and requires no external components or matching circuitry. The HMC553 operates with LO drive levels as low as +9 dBm and provides excellent LO to RF and LO to IF isolation due to optimized balun structures. Measurements were made with the chip mounted into in a 50 ohm test fixture and includes the parasitic effects of wire bond assembly. Connections were made with a 1 mil wire bond with minimal length (
