HMC620

HMC620 v01.1007 GaAs MMIC I/Q MIXER 3 - 7 GHz Typical Applications The HMC620 is ideal for: Point-to-Point Radios Features Wide IF Bandwidth: DC - 3.5 GHz High Image Rejection: 33 dB High LO to RF Isolation: 45 dB High Input IP3: +23 dB Die Size: 1.49 x 1.15 x 0.10 mm 3 MIXERS - CHIP Point-to-Multi-Point Radios WiMAX & Fixed Wireless VSAT www.DataSheet4U.com 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 fixture 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.
