| MICROWAVE CORPORATION v01.1002 HMC438MS8G SMT GaAs HBT MMIC DIVIDE-BY-5, DC - 7.0 GHz Features SSB Phase Noise: -153 dBc/Hz @100KHz Wide Bandwidth Output Power: -1 dBm Single DC Supply: +5V @ 80 mA MS8G SMT Package Typical Applications Prescaler for DC to C Band PLL Applications: * UNII, Pt. - Pt. & VSAT Radios * 802.11a & HiperLAN WLAN 10 FREQ. DIVIDER & DETECTORS - SMT * Fiber Optic * Cellular / 3G Infrastructure Functional Diagram General Description The HMC438MS8G is a low noise Divide-by-5 Static Divider utilizing InGaP GaAs HBT technology in a low cost 8 lead surface mount plastic package. This device operates from DC (with a square wave input) to 7.0 GHz input frequency from a single +5.0V DC supply. The low additive SSB phase noise of -153 dBc/Hz at 100 kHz offset helps the user maintain good 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 - 100 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 v01.1002 HMC438MS8G SMT GaAs HBT MMIC DIVIDE-BY-5, DC - 7.0 GHz Application Circuit 10 FREQ.
