PE64908 Datasheet | pSemi

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