Features
Divide-By-Two Low Phase Noise: -130 dBc/Hz @ 10KHz Miniature Small Outline Package: MSOP8
Single Positive Bias Voltage: +5V @ 27 mA
w r Ne o General Description ed f d men HMC251MS8 is a low noise divide-by-2 GaAs The om MMIC prescaler in an 8 lead surface mount MSOP Rec t plastic package. This device operates from 3.0 to No 6.5 GHz (input frequency) with a single +5V 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.

The circuit board used in the final application should be generated with proper RF circuit design techniques. Signal lines at RF IN and RF OUT should have 50 ohm impedance and the package ground leads should be connected directly to the ground plane similar to that shown. The evaluation circuit board shown is available from Hittite upon request.
