Hittite launches double-balanced mixer for 2-18GHz downconverter applications
Hittite Microwave Corp of Chelmsford, MA, USA (which designs and supplies analog, digital and mixed-signal RF, microwave and millimeter-wave ICs, modules and subsystems as well as instrumentation) has launched a new double-balanced mixer product suited to microwave and VSAT radios, sensors, test equipment and military & space applications.
The HMC1048LC3B is a GaAs MMIC, general-purpose, double-balanced mixer that can be used as a downconverter with DC to 4GHz at the IF port and 2 to 18GHz at the RF port. The mixer requires no external components or matching circuitry and exhibits what is claimed to be excellent LO/RF and LO/IF isolation due to optimized balun structures. The device operates with LO drive levels from +9dBm to +17dBm and provides a typical input IP3 of 23dBm. Suited to downconversion in satellite transponder applications, the HMC1048LC3B is housed in a compact ceramic 3mm x 3mm SMT package.
