Functional Diagram
General Description
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 frequen-
cies 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.
