HMC394LP4 / 394LP4E v09.0114 GaAs HBT PROGRAMMABLE 5-BIT COUNTER, DC - 2.2 GHz Typical Applications Features Programmable divider for offset synthesizer SSB Phase Noise: -153 dBc/Hz 100 kHz 4 4 and variable divide by N applications: Selectable Division from 2 to 32 Satellite Communication Systems Parallel 5-Bit Control t Point-to-Point and Point-to-Multi-Point Radios t Wide Input Power Range: -20 to +10 dBm LMDS 24 Lead 4x4mm QFN Package: 9 mm s s 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. et te ect The low additive SSB phase noise of -153 dBc/Hz at ect or ro 100 KHz offset makes this counter an excellent choice for low noise synthesizer applications. r r e e Electrical Specifications, T = +25 C, 50 Ohm System, Vcc= 5V A i i iv iv Parameter Conditions Min.
