HMC555 v02.0907 GaAs MMIC I/Q MIXER 31 - 38 GHz Typical Applications Features The HMC555 is ideal for: Wide IF Bandwidth: DC - 3.5 GHz Microwave Radio High Image Rejection: 17 dB Satellite Communication Systems High LO to RF Isolation: 50 dB 3 Military End Use High Input IP3: +21 dBm Test Equipment & Sensors Passive Topology: No DC Bias Required Compact Size: 1.49 x 1.15 x 0.1mm Functional Diagram General Description The HMC555 is a compact I/Q MMIC mixer which can be used as either an Image Reject Mixer or a Single Sideband Upconverter. The chip utilizes two double balanced mixer cells and a 90 degree hybrid fabricated in a GaAs MESFET process. All data shown below is taken with the chip mounted in a 50 Ohm test fi xture and includes the effects of 1 mil diameter x 12 mil length bond wires on each port. A low frequency quadrature hybrid was used to produce a 100 MHz USB IF output. This compact mixer is a much more compact alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies, and is ideal for microwave radio applications. The redundant IF port connections located on opposing sides of the HMC555 chip, provide added layout fl exibility. Electrical Specifi cations, T = +25 C, IF= 100 MHz, LO = +17 dBm* A Parameter Min.
