Functional Diagram
General Description
the HMc705LP4(e) is a low noise GaAs HBt
programmable divider in a 4x4 mm leadless surface
mount package. the divider can be programmed to
divide by any number from n = 1 to n = 17 up to
6.5 GHz. the HMc705LP4e’s high frequency
operation along with low phase noise floor is very
useful in high performance fast settling synthesizer
architectures. the HMc705LP4e may be combined
with Hittite’s Phase Frequency Detectors, vcos
and PLL ics to create low noise, fast settling phase
locked loops.
