Product Specification

PE64904

UltraCMOS^®Digitally Tunable Capacitor

(DTC) 100 - 3000 MHz

Product Description

Features

The PE64904 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.

 3-wire (SPI compatible) Serial Interface

with built-in bias voltage generation and

ESD protection

 DuNE™-enhanced UltraCMOS^®device

 5-bit 32-state Digitally Tunable Capacitor

The PE64904 offers high RF power handling and

ruggedness, while meeting challenging harmonic and

linearity requirements.

 Series configuration C = 0.60 - 4.60 pF

(7.7:1 tuning ratio) in discrete 129 fF steps

 Shunt configuration C = 1.14 - 5.10 pF

(4.6:1 tuning ratio) in discrete 129 fF steps

This highly versatile product can be used in series or shunt

configurations to support a wide variety of tuning circuit

topologies.

 High RF Power Handling (up to 38 dBm,

30 V_pkRF) and High Linearity

 Wide power supply range (2.3 to 3.6V)

and low current consumption

(typ. 140 μA at 2.6V)

The device is controlled through the widely supported

3-wire (SPI compatible) interface. All decoding and biasing

is integrated on-chip and no external bypassing or filtering

components are required.

 Excellent 1.5 kV HBM ESD tolerance

on all pins

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.

 2 x 2 x 0.45 mm QFN package

 Applications include:

 Tunable Filter Networks

 Tunable Antennas

 RFID

 Tunable Matching Networks

 Phase Shifters
