These DTC devices improve RF performance by offering tunability to applications ranging from filter banks to impedance matching networks. Peregrine DTCs also offer high power handling while meeting excellent harmonic and linearity requirements. Both SPI Compatible (3-wire) and I2C Compatible (2-wire) control interfaces versions are available.
Product Features
- Series configuration C = 0.7-4.6 pF (6.6:1 tuning ratio) in discrete 122 fF steps
- Shunt configuration C = 1.2-5.1 pF (4.3:1 tuning ratio) in discrete 122 fF steps
- High RF power handling : (>+38 dBm @ 50 Ω, 30 Vpk RF) and linearity
- Wide power supply range (2.3-3.6 V) and low current consumption (typ. 160 μA at 2.6 V)
- 3-wire (SPI compatible) Serial Interface with built-in bias voltage generation and ESD
- Exceptional 2 kV HBM ESD tolerance on all pins
Applications include:
- Tunable Filters Networks
- Tunable Antennas
- RFID
- Tunable Matching Networks
- Phase Shifters
- Wireless Communications
