v. DOWNCONVERTER, - GHz Typical Applications The is ideal for: Point-to-Point and Point-to-Multi-Point Radios Military Radar, EW & ELINT Satellite Communications Maritime & Mobile Radios Features Conversion Gain: db Image Rejection: dbc LO to RF Isolation: db Noise Figure:. db Input IP: dbm Lead x mm SMT Package Functional Diagram General Description The is a compact GaAs MMIC I/Q downconverter in a leadless x mm low stress injection molded plastic surface mount package. This device provides a small signal conversion gain of db with a noise figure of. db and dbc of image rejection. The 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/Q mixer outputs are provided and an external 9 hybrid is needed to select the required sideband. The 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.
