HMC557

HMC557 v01.1007 GaAs MMIC FUNDAMENTAL MIXER, 2.5 - 7.0 GHz Typical www.datasheet4u.com Applications Features High LO/RF Isolation: 48 dB Wide IF Bandwidth: DC - 3 GHz Passive Double Balanced Topology Low Conversion Loss: 7 dB Small Size: 1.02 x 0.94 x 0.1 mm The HMC557 is ideal for: WiMAX & Fixed Wireless 3 MIXERS - CHIP Microwave Radio Military & Space Communications, Radar & EW Test Equipment & Sensors Functional Diagram General Description The HMC557 is a passive double balanced mixer that can be used as an upconverter or downconverter between 2.5 and 7 GHz. The miniature monolithic mixer is fabricated in a GaAs MESFET process, and requires no external components or matching circuitry. The HMC557 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 (<12 mil).
