General Description
The HMC526 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 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 USB IF output. This product is a much smaller alternative to hybrid style Image Reject Mixers and Single Sideband Upconverter assemblies.

Features
   Wide IF Bandwidth: DC - 3.5 GHz
   Image Rejection: 40 dB
   LO to RF Isolation: 50 dB
   High Input IP3: +28 dBm

Typical Applications
The HMC526 is ideal for:
• Point-to-Point and Point-to-Multi-Point Radio
• VSAT
• Military End Use
