HMC144LC4 v02.1208 9 GaAs MMIC DOUBLE-BALANCED MIXER, 6 - 20 GHz Typical Applications Features The HMC144LC4 is ideal for: +23 dBm Input IP3 • Point-to-Point Radios 35 dB LO/RF Isolation • Point-to-Mulit-Point Radios & VSAT IF Bandwidth: DC to 3 GHz • Test Equipment & Sensors RoHS Compliant 4x4 mm SMT Package • Military End-Use MIXERS - SINGLE & DOUBLE BALANCED - SMT Functional Diagram General Description The HMC144LC4 is a Double-Balanced MMIC Mixer in a leadless “Pb free” SMT package which can be used as an upconverter or downconverter from 6 to 20 GHz. Broadband operation and 30 to 40 dB isolations are provided by on-chip baluns, which require no external components or DC bias. MMIC mixers are more reliable replacements to hybrid diode mixers assuring consistent conversion loss and isolation performance over high volume production lots. The HMC144LC4 eliminates the need for wire bonding, allowing use of surface mount manufacturing techniques. Electrical Specifi cations, TA = +25° C IF = 100 MHz LO = +20 dBm Parameter Min. Typ. Max.
