UltraCMOS® Digitally Tunable Capacitor

The PE64102 is a DuNE™-enhanced digitally tunable capacitor (DTC) based on pSemi’s UltraCMOS® technology. DTC products provide a monolithically integrated impedance tuning solution for demanding RF applications. They also offer a linear capacitance change versus tuning state and excellent harmonic performance compared to varactor-based tunable solutions.

This highly versatile product can be mounted in series or shunt configurations and uses a 3-wire (SPI compatible) serial interface. It has a high ESD rating of 2 kV HBM on all ports making this the ultimate in integration and ruggedness. The DTC will be offered in a standard 12-lead 2.0 × 2.0 × 0.55 mm QFN commercial package.

pSemi’s DuNE™ technology enhancements deliver high linearity and exceptional harmonics performance. It is an innovative feature of the UltraCMOS® process, providing performance superior to GaAs with the economy and integration of conventional CMOS.
