PE64907 is a DuNE™ technology-enhanced Digitally
Tunable Capacitor (DTC) based on Peregrine’s UltraCMOS®
technology. This highly versatile product supports a wide
variety of tuning circuit topologies with emphasis on
impedance matching and aperture tuning applications.
PE64907 offers high RF power handling and ruggedness
while meeting challenging harmonic and linearity
requirements enabled by Peregrine’s HaRP™ technology.
The device is controlled through the widely supported 3-wire
(SPI compatible) interface. All decoding and biasing is
integrated on-chip and no external bypassing or filtering
components are required.
DuNE™ devices feature ease of use while delivering
superior RF performance in the form of tuning accuracy,
monotonicity, tuning ratio, power handling, size, and quality
factor. With built-in bias voltage generation and ESD
protection, DTC products provide a monolithically integrated
tuning solution for demanding RF applications.
