HMC404 v03.0907 GaAs MMIC SUB-HARMONICALLY PUMPED IRM MIXER, 26 - 33 GHz Typical Applications Features The HMC404 is ideal for: Integrated LO Ampl ifier: +2 dBm Input 26 to 33 GHz Microwave Radios Sub-Harmonically Pumped (x2) LO Up and Down Converter for Image Rejection: 22 dB 3 Point-to-Point Radios Small Size: 1.90 x 1.25mm Satellite Communication Systems Functional Diagram General Description The HMC404 chip is a sub-harmonically pumped (x2) MMIC image rejection mixer with an integrated LO ampl ifier which can be used as an upconverter or downconverter. The chip utilizes a GaAs PHEMT technology that results in a small overall chip area of 2 2.31mm . The on-chip 90 hybrid provides excellent amplitude and phase balance resulting in greater than 22 dB of image rejection. The LO ampl ifier is a single bias (+4V) two stage design with only +2 dBm nominal drive required. Electrical Specifi cations, T = +25 C A IF = 1 GHz LO = +2 dBm & Vdd = +4V Parameter Units Min. Typ.
