HMC705LP4 / HMC705LP4E
v04.0212 Frequency Dividers & Detectors -SMT 6.5 GHz PROGRAMMABLE DIVIDER (N = 1 -17) Typical Applications Features The HMC705LP4(E) is ideal for: Ultra Low SSB Phase Noise Floor: -153 dBc/Hz @ 100 kHz • Satellite Communication Systems Programmable Divider (N= 1 -17) Operating up to 6.5 GHz • Point-to-Point Radios
• Military Applications 24 Lead 4X4mm SMT Package: 16mm 2 • Sonet Clock Generation
• Test Equipment 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. Electrical Specifications, TA = +25° C, Vcc = Vcc1 = Vcc2 = +5V
