Product Specification
PE64905
UltraCMOS® Digitally Tunable Capacitor
(DTC) 100 - 3000 MHz
Product Description
Features
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.
2-wire (I2C compatible) Serial Interface
with built-in bias voltage generation and
ESD protection
DuNE™-enhanced UltraCMOS® device
5-bit 32-state Digitally Tunable Capacitor
The PE64905 offers high RF power handling and
ruggedness, while meeting challenging harmonic and
linearity requirements.
Series configuration C = 0.60 - 4.60 pF
(7.7:1 tuning ratio) in discrete 129 fF steps
Shunt configuration C = 1.10 - 5.10 pF
(4.6:1 tuning ratio) in discrete 129 fF steps
This highly versatile product can be used in series or shunt
configurations to support a wide variety of tuning circuit
topologies.
High RF Power Handling (up to 38 dBm,
30 Vpk RF) and High Linearity
Wide power supply range (2.3 to 3.6V)
and low current consumption
(typ. 140 μA at 2.6V)
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.
Excellent 1.5 kV HBM ESD tolerance on
all pins
2 x 2 x 0.45 mm QFN package
Applications include:
Tunable Filter Networks
Tunable Antennas
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.
