Product Specification
PE64904
Product Description
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.
The PE64904 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
3-wire (SPI compatible) interface. 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.
