The HMC144LH5 is a Double-Balanced MMIC Mixer housed in a hermetic SMT leadless package which can be used as an upconverter or downconverter from 6 to 20 GHz. Broadband operation and excellent isolations are provided by on-chip baluns, while no external components or DC bias are required. The HMC144LH5 is a more reliable alternative to hybrid diode mixers, assuring consistent conversion loss and isolation performance over multiple production lots. The HMC144LH5 allows the use of surface mount manufacturing techniques and is suitable for high reliability, military, industrial and space applications.
