HMC558 v01.1007 GaAs MMIC FUNDAMENTAL MIXER, 5.5 - 14 GHz Typical Applications Features The HMC558 is ideal for: High LO/RF Isolation: 45 dB Microwave Radio Passive Double Balanced Topology Military & Space Low Conversion Loss: 7 dB Communications, Radar & EW Wide IF Bandwidth: DC - 6 GHz Test Equipment & Sensors Small Size: 0.91 x 0.94 x 0.1 mm 4 Functional Diagram General Description The HMC558 is a passive double balanced mixer that can be used as an upconverter or downconverter between 5.5 and 14 GHz. The miniature monolithic mixer is fabricated in a GaAs MESFET process, and requires no external components or matching circu- itry. The HMC558 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 para- sitic effects of wire bond assembly. Connections were made with a 1 mil wire bond with minimal length (<12 mil). Electrical Specifi cations, T = +25 C, IF= 100 MHz, LO= +15 dBm* A Parameter Min. Typ. Max. Min. Typ. Max.
