Introduction

The PE64905 is a DuNE™-enhanced Digitally Tunable Capacitor (DTC) based on Peregrine’s UltraCMOS® technology. DTC products provide a monolithically integrated impedance tuning solution for demanding RF applications. The PE64905 offers high RF power handling and ruggedness, while meeting challenging harmonic and linearity requirements. This highly versatile product can be used in series or shunt configurations to support a wide variety of tuning circuit topologies. The device is controlled through the widely supported 2- wire (RC compatible) interface and has two selectable addresses for implementations with multiple DTCs. All decoding and biasing is integrated on-chip, and no external bypassing, or filtering components are required. Peregrine’s 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.
