Digitally Tunable Capacitors (DTC)


Since 2011 Peregrine has been perfecting its product line of digitally tunable capacitors (DTCs), which enable RF circuits to perform optimally at many different frequencies. Peregrine’s UltraCMOS® DTCs support a wide range of applications in a variety of end markets, including antenna and filter tuning, and impedance matching between circuits. With a form factor five times smaller than competing technologies, UltraCMOS DTCs integrate high-Q tunable capacitors with a built-in low-voltage serial interface. Typical capacitance values range from 0.5 pF to 10 pF, with typical tuning ratios ranging from 3:1 to 6:1. The 5-bit, 32-state digitally controlled variable capacitors provide a monolithically integrated impedance tuning solution that enable wide-band tunable networks, minimize mismatch losses, improve system efficiency and reduce radio complexity. In addition to high power handling, Peregrine’s DTCs feature high linearity and a fast switching speed.

Peregrine’s DTCs are used for tunable filters and matching networks to RFID, antenna tuning and other wireless communications where tunability and optimal system performance is critical.
