Product Specification
PE64102
General Description
The PE64102 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 linear capacitance
change versus tuning state and excellent harmonic
performance compared to varactor-based tunable
solutions.
This highly versatile product can be mounted in series
or shunt configurations and uses a 3-wire (SPI
compatible) serial interface. It has a high ESD rating of
2 kV HBM on all ports making this the ultimate in
integration and ruggedness. The DTC will be offered in
a standard 12-lead 2.0 x 2.0 x 0.55 mm QFN
commercial 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.
