HMC925LC5 v01.0910 mixers - i/q mixers, IRMs & Receivers - SMT 9 GaAs MMIC I/Q UPCONVERTER 5.5 - 8.6 GHz Typical Applications Features The HMC925LC5 is ideal for: High Conversion Gain: 16.5 dB • Point-to-Point and Point-to-Multi-Point Radio Excellent Sideband Rejection: -30 dBc • Military Radar, EW & ELINT LO / RF Rejection: 22 dBc • Satellite Communications High Output IP3: +29 dBm • Sensors 32 Lead 5x5 mm SMT Ceramic Package: 25 mm² Functional Diagram General Description The HMC925LC5 is a compact GaAs MMIC I/Q upconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 16.5 dB with 30 dBc of sideband rejection. The HMC925LC5 utilizes a RF amplifier preceded by an I/Q mixer where the LO is driven by a driver amplifier. IF1 and IF2 mixer inputs are provided and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering of the unwanted sideband. The HMC925LC5 is a much smaller alternative to hybrid style single sideband upconverter assemblies and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.
