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
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
PLLs 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
and are supported by ADI’s popular
™, 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
