    Overview

    PE64909 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 an emphasis on impedance matching and aperture tuning applications. PE64909 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 are 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.

    Features

        3-wire (SPI compatible) serial interface with built-in bias voltage generation and ESD protection
        DuNE™ technology-enhanced
        4-bit 16-state digitally tunable capacitor
        Shunt configuration C = 0.6 pF to 2.35 pF (3.9:1 tuning ratio) in discrete 117 fF steps
        High RF power handling (30 Vpk RF) and linearity
        Wide power supply range (2.3 to 4.8V) and low current consumption (typ. 140 μA at 2.75V)
        High ESD tolerance of 2kV HBM on all pins
        Packaging: 10-lead 2 × 2 × 0.55 mm QFN
