HMC525

HMC525 v00.1104 www.DataSheet4U.com GaAs MMIC I/Q MIXER 4.0 - 8.5 GHz Typical Applications The HMC525 is ideal for: Point-to-Point and Point-to-Multi-Point Radio Features Wide IF Bandwidth: DC - 3.5 GHz Image Rejection: 40 dB LO to RF Isolation: 50 dB High Input IP3: +23 dBm 3 MIXERS - CHIP VSAT Functional Diagram General Description The HMC525 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 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 USB IF output. This product is a much smaller alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies.
