| v01.1002 MICROWAVE CORPORATION HMC434 SMT GaAs HBT MMIC DIVIDE-BY-8, DC - 8.0 GHz Features Ultra Low SSB Phase Noise: -150 dBc/Hz Single-Ended I/O's Output Power: -2 dBm Single DC Supply: +3V @ 62 mA 9 mm2 Ultra Small Package: SOT26 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 HMC434 is a low noise Divide-by-8 Static Divider utilizing InGaP GaAs HBT technology in an ultra small surface mount SOT26 plastic package. This device operates from DC (with a square wave input) to 8.0 GHz input frequency with a single +3.0V DC supply. Single-ended inputs and outputs reduce component count and cost. The low additive SSB phase noise of -150 dBc/Hz at 100 kHz offset helps the user maintain good system noise performance.
