Richardson RFPD Inc. announces four new DuNE™ technology-enhanced digitally tunable capacitors (DTCs) from Peregrine Semiconductor Corp. (Peregrine).
The new DTCs are the latest additions to Peregrine industry-leading integrated RF tuning IC portfolio and feature a wide capacitance range of 0.6 to 7.7 pF and support power handling up to 34 dBm into 50 Ohms (30 Vpk RF). They include integrated bias generation, RF filtering and bypassing, control interface, and ESD protection of 2 kV HBM, all on a 2 mm x 2 mm package.
HaRP™ technology enhancements allow for high linearity of IIP3 >+65 dBm at 50 Ohms and harmonic performance of 2fo/3fo = -40/-40 dBm @ 34 dBm RF (900 MHz), and 32 dBm RF (1900 MHz). The devices feature direct battery voltage operation, with consistent performance enabled by on-chip voltage regulation. Low supply and standby currents of 140 and 24 microamperes (VDD = 2.75V), respectively, help to extend battery life in portable devices. The devices are controlled through the widely-supported 3-wire (SPI-compatible) interface, making it easy to incorporate them into designs.
The new DTCs provide a monolithically integrated impedance tuning solution for demanding RF applications, including radio-frequency identification (RFID), military radio, test and measurement, M2M, and wireless infrastructure.
