| MICROWAVE CORPORATION HMC147S8 General Description 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.

Signal lines should have 50 ohm impedance while the package ground leads should be connected directly to the ground plane similar to that shown above. The evaluation circuit board as shown is available from Hittite upon request. 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 4 - 41 SMT |
