HMC329 v04.1007 GaAs MMIC DOUBLE-BALANCED MIXER, 25 - 40 GHz Typical Applications Features The HMC329 is ideal for: Passive: No DC Bias Required LMDS Input IP3: +19 dBm Microwave Point-to-Point Radios LO/RF Isolation: 42 dB SATCOM Small Size: 0.85 x 0.55 x 0.1 mm 4 Functional Diagram General Description The HMC329 chip is a miniature passive double balanced mixer which can be used as an upconverter or downconverter from 25-40 GHz in a small chip area of 0.85 x 0.55 mm. Excellent isolations are provided by on-chip baluns, and the chip requires no external components and no DC bias. Measurements were made with the chip mounted and ribbon bonded into in a 50-ohm microstrip test fi xture that contains 5-mil alumina substrates between the chip and K-connectors. Measured data includes the parasitic effects of the assembly. RF connections to the chip were made with 0.076 mm (3-mil) ribbon bond with minimal length <0.31mm (<12 mil).
