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.

Operating Notes:
1. With no input signal, or input signals below the minimum input power level, the prescaler will self-oscillate.
2. DC blocks on the RF ports are not required but are recommended if DC voltages exceeding 8 volts are present.

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.
