Typical Applications
The HMC251MS8 is ideal for:
Wireless
Local
Loop
UNII & HiperLAN
ISM
VSAT
Note 1. Output Power Measured at half the Input Frequency.
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 recom-
mended if DC voltages exceeding 8 volts are present.

The circuit board used in the fi nal 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.
