Analog
Devices, Inc. announced 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:
- Divide by 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
PLLshttp://www.analog.com/pr/adf5000.
