HMC394LP4 / 394LP4E
GaAs HBT PROGRAMMABLE
5-BIT COUNTER, DC - 2.2 GHz
v09.0114
General Description
Features
Functional Diagram
The HMC394LP4 & HMC394LP4E are low noise
GaAs HBT programmable 5-bit counters in 4 x
4mm leadless surface mount packages. This device
allows continuous division from N= 2 to 32 at input
frequencies 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 applications.
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
24 Lead 4x4mm QFN Package: 9 mm²
Electrical Specications, T
A
= +25° C, 50 Ohm System, Vcc= 5V
Typical Applications
