Product Description The PE64904 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 PE64904 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 3-wire (SPI compatible) interface. 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. Product Specification UltraCMOS® Digitally Tunable Capacitor (DTC) 100 - 3000 MHz PE64904 Features 3-wire (SPI compatible) Serial Interface with built-in bias voltage generation and ESD protection DuNE™-enhanced UltraCMOS® device 5-bit 32-state Digitally Tunable Capacitor Series configuration C = 0.60 - 4.60 pF (7.7:1 tuning ratio) in discrete 129 fF steps Shunt configuration C = 1.14 - 5.10 pF (4.6:1 tuning ratio) in discrete 129 fF steps 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) 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 RFID Tunable Matching Networks Phase Shifters Wireless Communications Figure 2.
