The mixer provides exceptional isolation and inter-modulation performance for appli- cation in high signal density environments. This device can also be used as a biphase modulator or demodulator. The MSOP8 is the smallest footprint available for a com- plete double-balanced mixer (0.118" x 0.190" x 0.040"). IP3 (INPUT): +18 dBm . .

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. 21 Cabot Road, Woburn, MA 01801 Phone: 781-933-7267 Fax: 781-932-8903 Web Site: www.hittite.com 4-61
