HMC394LP4
GaAs HBT PROGRAMMABLE
5-BIT COUNTER, DC - 2.2 GHz
v04.1102
General Description
Features
Functional Diagram
The HMC394LP4 is a low noise GaAs HBT pro-
grammable 5-bit counter in a 4mm x 4mm lead-
less surface mount package. This device allows
continuous division from N= 2 to 32 at input fre-
quencies up to 2.2 GHz. The output voltage swing
is 800 mV with a duty cycle inversely proportional
to N. The low additive SSB phase noise of -153
dBc/Hz at 100 KHz offset makes this counter an
excellent choice for low noise synthesizer appli-
cations.
SSB Phase Noise: -153 dBc/Hz @ 100 kHz
Selectable Division from 2 to 32
Parallel 5-Bit Control
Wide Input Power Range: -20 to +10 dBm
4mm x 4mm Leadless SMT Package

= +25 C, 50 Ohm System, Vcc= 5V
Typical Applications
Programmable divider for offset synthesizer
and variable divide by N applications:
Satellite Communication Systems
Pt-Pt and Pt-MPt Radios
LMDS
SONET
1. Divider will operate down to DC for square-wave input signal.
