DIVIDER & DETECTORS - SMT * Military Functional Diagram General Description The HMC492LP3 is a low noise Divide-by-2 Static Divider utilizing InGaP GaAs HBT technology packaged in a leadless 3x3 mm QFN surface mount plastic package. This device operates from DC (with a square wave input) to 18 GHz input frequency from a single +5.0V DC supply. The low additive SSB phase noise of -150 dBc/Hz at 100 kHz offset helps the user maintain excellent system noise performance.

Signal lines should have 50 ohm impedance while the package ground leads and backside ground slug should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request. This evaluation board is designed for single ended input testing. J2 and J3 provide differential output signals. * Circuit Board Material: Rogers 4350 10 - 122 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com MICROWAVE CORPORATION v01.0604 HMC492LP3 SMT GaAs HBT MMIC DIVIDE-BY-2, DC - 18 GHz Application Circuit FREQ.
