Product Specification PE64908 UltraCMOS Digitally Tunable Capacitor (DTC) 100-3000 MHz Product Description Features PE64908 is a DuNE technology-enhanced Digitally 3-wire (SPI compatible) serial interface Tunable Capacitor (DTC) based on Peregrines UltraCMOS with built-in bias voltage generation and technology.This highly versatile product supports a wide ESD protection variety of tuning circuit topologies with emphasis on DuNE technology enhanced impedance matching and aperture tuning applications. 5-bit 32-state Digitally Tunable Capacitor PE64908 offers high RF power handling and ruggedness Shunt configuration C = 2.15 pF to 7.7 pF (3.6:1 tuning ratio) in discrete 180 fF while meeting challenging harmonic and linearity steps requirements enabled by Peregrines HaRP technology. High RF power handling (30 V RF) and pk The device is controlled through the widely supported 3-wire linearity (SPI compatible) interface. All decoding and biasing is Wide power supply range (2.3 to 4.8V) for integrated on-chip and no external bypassing or filtering and low current consumption components are required. (typ. 140 A at 2.75V) High ESD tolerance of 2kV HBM on all DuNE devices feature ease of use while delivering pins superior RF performance in the form of tuning accuracy, Applications include: monotonicity, tuning ratio, power handling, size, and quality Tunable antennas factor. With built-in bias voltage generation and ESD Tunable matching networks protection, DTC products provide a monolithically integrated Tunable filter networks tuning solution for demanding RF applications.
