HMC394LP4 / 394LP4E
v09.0114 Frequency Dividers & Detectors -SMT 4 GaAs HBT PROGRAMMABLE
5-BIT COUNTER, DC -2.2 GHz Typical Applications Features Programmable divider for offset synthesizer
and variable divide by N applications: SSB Phase Noise: -153 dBc/Hz @ 100 kHz • Satellite Communication Systems Parallel 5-Bit Control • Point-to-Point and Point-to-Multi-Point Radios Wide Input Power Range: -20 to +10 dBm • LMDS 24 Lead 4x4mm QFN Package: 9 mm² Selectable Division from 2 to 32 • SONET 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
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. Electrical Specifications, TA = +25° C, 50 Ohm System, Vcc= 5V
