HMC147S8 MICROWAVE CORPORATION GaAs MMIC SMT DOUBLE-BALANCED MIXER 1.6 - 3.4 GHz FEBRUARY 2001 Features General Description CONVERSION LOSS: 8.5 dB The HMC147S8 is a miniature double-balanced mixer in a plastic surface mount SmallOutline IC (SOIC) package. The device can be used as an upconverter or downconverter and is especially suitable for base station and portable wireless applications because of its small size and zero DC bias requirement. The mixer provides exceptional isolation and intermodulation performance for application in high signal density environments. This device can also be used as a biphase modulator/demodulator, or Phase Comparator. See the smaller MSOP8 Packaged Equivalent mixer HMC175MS8.
