Hittite's New 2 GHz Low-Noise Programmable Frequency Divider
(divide-by-1-to-4)
Exceptional Noise Performance in a 3 x 3 mm Package
 Chelmsford,
MA, 02/16/2010 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for
performance driven RF and microwave transceivers is introducing a new low-noise, programmable frequency divider
within a small 3 x 3 mm, leadless SMT, quad flatpack which is designed to accommodate power sensitive applications
with uncompromising noise performance.
 The
HMC794LP3E frequency divider provides four, hardware selectable, integer divider settings for input signals up
to 2 GHz: divide-by-1-to-4. Phase noise performance levels (with fIN = 2 GHz) is typically below -160 dBc/Hz @ 100
kHz offset; tapering out to a residual noise floor below -166 dBc/Hz @ 10 MHz. The SiGe BiCMOS structures provide
consistent output power regardless of divider setting, signal frequency, temperature, and supply voltage. The
device is powered from a 5V supply, and incorporates a power down feature, good input-output isolation, external
output power adjustment and 50% output duty cycle.
HMC794LP3E is ideal for applications in which phase noise performance is the critical parameter, and/or
require a selectable divide ratio, such as clock and LO signal generation for instrumentation, software defined
radios, and multi-band synthesizers. Other interesting applications include fast switching “ping-pong” between two
signal sources via complementary “chip enable” controls on two dividers for complete source isolation at the
divided output frequencies.
Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via
the company’s e-commerce site or via direct purchase order. Released data sheets are available on-line at
www.hittite.com.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
