v3.1 HMC98LC Typical Applications The HMC98LC is ideal for: Point-to-Point and Point-to-Multi-Point Radio Military Radar, EW & ELINT Satellite Communications Maritime & Mobile Radio Functional Diagram Features Electrical Specifications, T A = + C, IF = 1 MHz, LO = dbm, VD1 = VD = 3V, VD3 = V* Conversion Gain: 11 db Image Rejection: db LO to RF Isolation: db Noise Figure:. db Input IP3: + dbm 3 Lead xmm Ceramic SMT Package: mm² General Description The HMC98LC is a compact GaAs MCM I/Q downconverter in a leadless RoHS compliant SMT ceramic package. This device provides a small signal conversion gain of 11 db with a noise figure of. db and db of image rejection. The HMC98LC 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 9 hybrid is needed to select the required sideband. The HMC98LC 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.
