HMC557RF/IF射频/中频RFID的射频混频器规格书PDF中文资料

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 fi xture and includes the parasitic effects of wire bond assembly. Connections were made with a 1 mil wire bond with minimal length (
