v03.0907 Typical Applications The HMC404 is ideal for: 26 to 33 GHz Microwave Radios 3 Up and Down Converter for Point-to-Point Radios Satellite Communication Systems Functional Diagram HMC404 GaAs MMIC SUB-HARMONICALLY PUMPED IRM MIXER, 26 - 33 GHz Features Integrated LO Amplifier: +2 dBm Input Sub-Harmonically Pumped (x2) LO Image Rejection: 22 dB Small Size: 1.90 x 1.25mm General Description The HMC404 chip is a sub-harmonically pumped (x2) MMIC image rejection mixer with an integrated LO amplifier 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 2.31mm2. The on-chip 90° hybrid provides excellent amplitude and phase balance resulting in greater than 22 dB of image rejection. The LO amplifier is a single bias (+4V) two stage design with only +2 dBm nominal drive required.
