| HMC438MS8G / 438MS8GE v03.0705 SMT GaAs HBT MMIC DIVIDE-BY-5, DC - 7.0 GHz Typical Applications Features SSB Phase Noise: -153 dBc/Hz @100KHz Wide Bandwidth Output Power: -1 dBm Single DC Supply: +5V @ 80 mA MS8G SMT Package 6 FREQUENCY DIVIDERS & DETECTORS - SMT Prescaler for DC to C Band PLL Applications: * UNII, Point-to-Point & VSAT Radios * 802.11a & HiperLAN WLAN * Fiber Optic * Cellular / 3G Infrastructure Functional Diagram General Description The HMC438MS8G & HMC438MS8GE are low noise Divide-by-5 Static Dividers utilizing InGaP GaAs HBT technology in low cost 8 lead surface mount plastic packages. 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. 6 - 94 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC438MS8G / 438MS8GE v03.0705 SMT GaAs HBT MMIC DIVIDE-BY-5, DC - 7.0 GHz Application Circuit 6 FREQUENCY DIVIDERS & DETECTORS - SMT For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com 6 - 95 |
