pSemi UltraCMOS® Digitally Tunable Capacitors

pSemi UltraCMOS® Digitally Tunable Capacitors (DTCs) are DuNE™ technology-enhanced devices designed to support various tuning circuit topologies with emphasis on impedance matching and aperture tuning applications. pSemi UltraCMOS DTCs offer high RF power handling and ruggedness while meeting challenging harmonic and linearity requirements. These devices are controlled through the widely supported 3-wire (SPI compatible) interface. All decoding and biasing are integrated on-chip, and no external bypassing or filtering components are required.

Peregrine DuNE technology enables excellent linearity and exceptional harmonic performance. DuNE devices deliver performance superior to GaAs devices with the economy and integration of conventional CMOS. With built-in bias voltage generation and ESD protection, DTC products provide a monolithically integrated tuning solution for demanding RF applications.
