HMC338

MIXERS - SUB-HARMONIC - CHIP v03.1007 Typical Applications The HMC338 is ideal for: General Purpose Applications 3 26 and 33 GHz Microwave Radios Up and Down Converter for Point-to-Point Radios Satellite Communication Systems Functional Diagram HMC338 GaAs MMIC SUB-HARMONICALLY PUMPED MIXER, 26 - 33 GHz Features Integrated LO Amplifier: -5 dBm Input Sub-Harmonically Pumped (x2) LO High 2LO/RF Isolation: 33 dB Die Size: 1.32 x 0.97 x 0.1 mm General Description The HMC338 chip is a general purpose sub-harmonically pumped (x2) MMIC mixer with an integrated LO amplifier which can be used as an upconverter or downconverter in the 26 to 33 GHz frequency range. The chip utilizes a GaAs PHEMT technology that results in a small overall chip area of 1.28mm2. The 2LO to RF isolation is excellent eliminating the need for additional filtering. The LO amplifier is a single bias (+3V to +4V) two stage design with only -5 dBm nominal drive requirement. All data is measured with the chip in a 50 ohm test fixture connected via 0.076 mm (3 mil) ribbon bonds of minimal length <0.31 mm (<12 mils). 3 - 42 Electrical Specifications, TA = +25° C, As a Function of Vdd Parameter Frequency Range, RF Frequency Range, LO Frequency Range, IF Conversion Loss Noise Figure (SSB) 2LO to RF Isolation 2LO to IF Isolation IP3 (Input) 1 dB Compression (Input) Supply Current (Idd) IF = 1 GHz LO = -5 dBm & Vdd = +4V Min.
