GENERAL DESCRIPTION The HMC1048ALC3B is a general-purpose, monolithic microwave integrated circuit (MMIC), double balanced mixer that can be used as a downconverter with dc to 4 GHz at the intermediate frequency (IF) port and 2.25 GHz to 18 GHz at the radio frequency (RF) port. The mixer requires no external components or matching circuitry. The HMC1048ALC3B provides excellent local oscillator (LO) to R F, LO t o I F, and RF to IF isolation. The mixer operates with LO drive levels from 9 dBm to 17 dBm. The HMC1048ALC3B eliminates the need for wire bonding and allows the use of surface- mount manufacturing techniques.
