HMC330

MICROWAVE CORPORATION v01.0301 HMC330 GaAs MMIC SUB-HARMONICALLY PUMPED MIXER, 25 - 40 GHz Features Sub-Harmonically Pumped (x2) LO Input IP3: 17 dBm 2LO/RF Isolation: 48 dB Small Size: 0.97 mm2 Typical Applications The HMC330 is ideal for: LMDS Point-to-Point Radios SATCOM Functional Diagram General Description The HMC330 MMIC is a broadband double balanced sub-harmonically pumped passive mixer that may be used as an upconverter or downconverter. The mixer requires no external matching or bias. This design was optimized to provide better 1dB compression performance as compared to the HMC266 under the same LO drive levels. The HMC330 provides greater than 38 dB LO to RF and 2LO to RF isolation performance. Measurements were made with the chip mounted and ribbon bonded into a 50-ohm microstrip test fixture 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). 5 MIXERS - CHIP Electrical Specifications, TA = +25° C LO = +14 dBm, IF = 2.5 GHz Parameter Min.
