HMC251MS8 v01.0801 GaAs MMIC SMT DIVIDE-BY-2, 3.0 - 6.5 GHz FREQ. DIVIDERS & DETECTORS - SMT 10 Typical Applications Features The HMC251MS8 is ideal for: Divide-By-Two • Wireless Local Loop Low Phase Noise: -130 dBc/Hz @ 10KHz • UNII & HiperLAN Single Positive Bias Voltage: +5.0V @ 27 mA • ISM Miniature Small Outline Pakcage: MSOP8 • VSAT Functional Diagram General Description The HMC251MS8 is a low noise divide-by-2 GaAs MMIC prescaler in an 8 lead surface mount MSOP plastic package. This device operates from 3.0 to 6.5 GHz (input frequency) with a single +5.0 V DC supply while drawing only 27 mA of current. The low residual phase noise of this prescaler helps the user maintain good system noise performance.
