Analog Devices Press Release - May 10, 2010
Analog Devices Introduces Low-Power Radio Frequency Prescalers
Complementing ADI’s industry-leading PLL synthesizers, the ADF500x RF prescaler circuits operate up to 18 GHz
with very low power consumption.
Analog Devices, Inc. (ADI), a global leader in
high-performance semiconductors for signal-processing applications and leading provider of RF ICs (radio frequency
integrated circuits), announced today the availability of new
RF prescaler circuits for a variety of applications, including point-to-point radios, VSATs (very small
aperture terminals) and microwave communication systems. A prescaler is a circuit that generates an output signal
related to an input signal by a fractional scale factor. Designed using ADI’s industry-leading RF and PLL (phase
locked loop) synthesizer design expertise, the
ADF500x RF prescalers offer the industry’s highest performance for a fixed divide ratio of 2, 4 or 8 and can
operate to 18 GHz with very low power consumption.
Using a nominal 3-V supply, the ADF500x devices have differential 100 Ω RF outputs that allow a direct
interface to the differential RF inputs of ADI’s PLL products. This launch of the ADF500x series of products
includes three new devices: the
ADF5000 divide-by-2 prescaler;
ADF5001 divide-by-4 prescaler and
ADF5002 divide-by-8 prescaler.
ADF500x Prescaler Features and Benefits:
2, 4 or 8 options
Integrated RF de-coupling capacitors
Low power consumption: active mode at 30 mA and
power down mode at 7 mA
Low phase noise at -150 dBc/Hz
Single DC supply that is +3V compatible with ADI’s
extensive offering of
Pricing, Availability, Tools and Complementary Products
The ADF500x RF prescalers are available now in 3 mm x 3 mm LFCSP packaging and are priced at $6.97
per unit in 10,000-unit quantities. They complement ADI’s wide range of
PLL products and are supported by ADI’s popular
ADIsimPLL™, a free downloadable design tool available at
that enables the rapid and reliable evaluation of high-performance PLL products by performing simulations of all
key performance variables. More information, including complete data sheets, is available at

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...
