Digitally tunable capacitors PE641010 pages

Product Specification
PE64101
UltraCMOS® Digitally Tunable Capacitor
(DTC) 100 - 3000 MHz

Product Description
The PE64101 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. They also offer a cost-effective tunable
capacitor with excellent linearity and ESD performance.
This highly versatile product can be mounted in series or
shunt configuration and is controlled by a 3-wire (SPI
compatible) serial interface. High ESD rating of 2 kV
HBM on all ports making this the ultimate in integration
and ruggedness. The DTC is offered in a standard 12lead 2.0 x 2.0 x 0.55 mm QFN package.
Peregrine’s DuNE™ technology enhancements deliver
high linearity and exceptional harmonics performance. It
is an innovative feature of the UltraCMOS® process,
providing performance superior to GaAs with the
economy and integration of conventional CMOS.
