HMC426MS8 / 426MS8E v00.0903 SMT SiGe MMIC DIVIDE-BY-4, DC - 4 GHz 6 FREQUENCY DIVIDERS & DETECTORS - SMT Typical Applications Prescaler for DC to 4.0 GHz PLL Applications: • DBS/CATV Tuners • 802.11x & HiperLAN WLAN • Fixed Wireless & WLL • Microwave & VSAT Radios • Cellular & 3G Features Ultra Low SSB Phase Noise: -146 dBc/Hz Wide Input Power Range: -15 to +10 dBm Output Power: +3.5 dBm Single DC Supply: +3V @ 13 mA MS8 SMT Package Functional Diagram General Description The HMC426MS8 & HMC426MS8E are low noise Divide-by-4 Static Dividers utilizing SiGe technology in 8 lead surface mount plastic packages. 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.
