HMC705LP4 / HMC705LP4E
v04.0212
6.5 GHz PROGRAMMABLE DIVIDER (N = 1 - 17)
General Description
Features
Functional Diagram
Typical Applications
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 oor 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

The circuit board used in the application should use
RF circuit design techniques. Signal lines should have
50 Ohm impedance while the package ground leads
and backside ground paddle should be connected
directly to the ground plane similar to that shown. A
sufficient number of via holes should be used to con-
nect the top and bottom ground planes. The evalua-
tion circuit board shown is available from Hittite upon
request.
