HMC426MS8 v00.0903 MICROWAVE CORPORATION SMT SiGe MMIC DIVIDE-BY-4, DC - 4.0 GHz 10 Typical Applications Features Prescaler for DC to 4.0 GHz PLL Applications: Ultra Low SSB Phase Noise: -146 dBc/Hz • DBS/CATV Tuners Wide Input Power Range: -15 to +10 dBm • 802.11x & HiperLAN WLAN Output Power: +3.5 dBm • Fixed Wireless & WLL Single DC Supply: +3V @ 13 mA • Microwave & VSAT Radios MS8 SMT Package FREQ. DIVIDER & DETECTORS - SMT • Cellular & 3G Functional Diagram General Description The HMC426MS8 is a low noise Divide-by-4 Static Divider utilizing SiGe technology in an 8 lead surface mount plastic package. This device operates from DC (with a square wave input) to 4.0 GHz input frequency while operating from a single +3V supply at only 13 mA. The low additive SSB phase noise of -146 dBc/Hz at 100 kHz offset helps the user maintain excellent system noise performance.

U1 HMC426MS8 Divide-by-4 PCB* 107620 Eval Board The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads 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 and output testing. * Circuit Board Material: Rogers 4350 10 - 70 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 v00.0903 MICROWAVE CORPORATION HMC426MS8 SMT SiGe MMIC DIVIDE-BY-4, DC - 4.0 GHz Application Circuit FREQ.
