HMC951LP4E v01.0511 mixers - i/q mixers, IRMs & Receivers - SMT 9 GaAs MMIC I/Q DOWNCONVERTER 5.6 - 8.6 GHz Typical Applications Features The HMC951LP4E is ideal for: Conversion Gain: 13 dB • Point-to-Point and Point-to-Multi-Point Radio Image Rejection: 20 dB • Military Radar, EW & ELINT LO to RF Isolation: 48 dB • Satellite Communications Noise Figure: 2.3 dB Input IP3: 3 dBm 24 Lead 4x4 mm SMT Package: 16 mm² Functional Diagram General Description The HMC951LP4E is a compact GaAs MMIC I/Q downconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 13 dB with a noise figure of 2 dB and 25 dB of image rejection across the frequency band. The HMC951LP4E utilizes an LNA followed by an image reject mixer which is driven by an LO buffer amplifier. The image reject mixer eliminates the need for a filter following the LNA, and removes thermal noise at the image frequency. I and Q mixer outputs are provided and an external 90° hybrid is needed to select the required sideband. The HMC951LP4E is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and is compatible with surface mount manufacturing techniques.
