| HMC571LC5 v05..0208 GaAs MMIC I/Q DOWNCONVERTER 21 - 25 GHz Typical Applications The HMC571LC5 is ideal for: * Point-to-Point and Point-to-Multi-Point Radio Features 9 dB Conversion Gain Image Rejection: 18 dB 2 LO to RF Isolation: 35 dB Noise Figure: 3.0 dB Input IP3: +2 dBm 8 MIXERS - I/Q RECEIVERS - SMT * Military Radar, EW & ELINT * Satellite Communications RoHS Compliant 5x5 mm SMT Package Functional Diagram General Description The HMC571LC5 is a compact GaAs MMIC I/Q downconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 9 dB with a noise figure of 3.0 dB and 18 dB of image rejection across the frequency band. The HMC571LC5 utilizes an LNA followed by an image reject mixer which is driven by an active x2 multiplier. 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 HMC571LC5 is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.
