| v01.0801 MICROWAVE CORPORATION HMC251MS8 GaAs MMIC SMT DIVIDE-BY-2, 3.0 - 6.5 GHz Features Divide-By-Two Low Phase Noise: -130 dBc/Hz @ 10KHz Single Positive Bias Voltage: +5.0V @ 27 mA Miniature Small Outline Pakcage: MSOP8 Typical Applications The HMC251MS8 is ideal for: * Wireless Local Loop * UNII & HiperLAN 10 FREQ. DIVIDER & DETECTORS - SMT * ISM * 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.
