| HMC434 / 434E v02.0705 SMT GaAs HBT MMIC DIVIDE-BY-8, DC - 8.0 GHz 5 FREQUENCY DIVIDERS & DETECTORS - SMT Typical Applications Prescaler for DC to C Band PLL Applications: * UNII, Pt. - Pt. & VSAT Radios * 802.11a & HiperLAN WLAN * Fiber Optic * Cellular / 3G Infrastructure 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 Functional Diagram General Description The HMC434 & HMC434E are low noise Divide-by-8 Static Dividers utilizing InGaP GaAs HBT technology in ultra small surface mount SOT26 plastic packages. 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.
