Product Specification
PE64905
Product Description
The PE64905 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 PE64905 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 2-wire
(I
2
C compatible) interface and has two selectable addresses
for implementations with multiple DTCs. 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.
