HMC265LM3

MIXERS - SUB-HARMONIC - SMT v01.1201 Typical Applications The HMC265LM3 is ideal for: 20 and 31 GHz Microwave Radios 8 Downconverter for Point to Point Radios LMDS and SATCOM Functional Diagram HMC265LM3 GaAs MMIC SUB-HARMONIC SMT MIXER, 20 - 31 GHz Features Integrated LO Amplifier: -4 dBm Input Sub-Harmonically Pumped (x2) LO High 2LO/RF Isolation: > 28 dB LM3 SMT Package General Description The HMC265LM3 is a 20 - 31 GHz surface mount sub-harmonically pumped (x2) MMIC mixer downconverter with integrated LO and IF amplifiers in a SMT leadless chip carrier package. The 2LO to RF and IF isolations are an excellent 28 to 47 dB, eliminating the need for additional filtering. The LO amplifier is a single bias (+3V to +4V) two stage design with only -4 dBm drive requirement. All data is with the non-hermetic, epoxy sealed LM3 packaged device mounted in a 50 ohm test fixture. Utilizing the HMC265LM3 eliminates the need for wirebonding, thereby providing a consistent connection interface for the customer. 8 - 30 Electrical Specifications, TA = +25° C, As a Function of Vdd Parameter IF = 2 GHz LO = -4 dBm & Vdd = +4V Min.
