Description

PE64906 is a DuNE™ technology-enhanced digitally tunable capacitor (DTC) based on pSemi’s UltraCMOS® technology. This highly versatile product supports a wide variety of tuning circuit topologies with emphasis on impedance matching and aperture tuning applications. PE64906 offers high RF power handling and ruggedness while meeting challenging harmonic and linearity requirements enabled by pSemi’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.
