6.5 GHz PROGRAMMABLE

DIVIDER (N = 1 - 17)

v03.0709

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.

ultra Low ssB Phase noise Floor:

-153 dBc/Hz @ 100 kHz

Programmable Divider (n= 1 - 17) operating

up to 6.5 GHz

the HMc705LP4(e) is ideal for:

• satellite communication systems

• Point-to-Point radios

• Military Applications

• sonet clock Generation

• test equipment
