HMC394LP4 / HMC394LP4E

The HMC394LP4(E) is a low noise GaAs HBT programmable 5-bit counter in 4x4 mm leadless surface mount package. This HMC394LP4(E) 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.
