HMC620 v01.1007 GaAs MMIC I/Q MIXER 3 - 7 GHz Typical Applications Features The HMC620 is ideal for: Wide IF Bandwidth: DC - 3.5 GHz Point-to-Point Radios High Image Rejection: 33 dB Point-to-Multi-Point Radios High LO to RF Isolation: 45 dB 3 WiMAX & Fixed Wireless High Input IP3: +23 dB VSAT Die Size: 1.49 x 1.15 x 0.10 mm Functional Diagram General Description The HMC620 is a compact I/Q MMIC mixer which can be used as either an Image Reject Mixer (IRM) or a Single Sideband Upconverter. The chip utilizes two standard Hittite 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 20 mil length bond wires on each port. A low frequency quadrature hybrid was used to produce a 100 MHz upper side band (USB) IF output. This product is a much smaller and more consistent alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies.
