71-0066-01

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 (I2C 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.

Table 2. Pin Descriptions

Exceeding absolute maximum ratings may cause

permanent damage. Operation should be restricted

to the limits in the Operating Ranges table.

Operation between operating range maximum and

absolute maximum for extended periods may reduce

reliability.

Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOS®

devices are immune to latch-up.

Electrostatic Discharge (ESD) Precautions

When handling this UltraCMOS® device, observe

the same precautions that you would use with other

ESD-sensitive devices. Although this device

contains circuitry to protect it from damage due to

ESD, precautions should be taken to avoid

exceeding the specified rating.

Moisture Sensitivity Level

The Moisture Sensitivity Level rating for the

PE64905 in the 10-lead 2 x 2 x 0.45 mm QFN

package is MSL1.

Note: 1. De-rated over frequency

Note: 1. Pins 1-2 and 8-9 must be tied together on PCB for optimal performance
