Peregrine introduces 1.7 to 2.2GHz Digital Phase Shifter
RF SOI device provides high linearity for active antenna applications
Peregrine Semiconductor, founder of RF SOI (silicon on insulator), has introduced the UltraCMOS PE44820, an 8-bit digital phase shifter that covers a 358.6-degree phase range.
This monolithic, digitally controlled product is said to deliver exceptional phase accuracy and linearity. Supporting a frequency range of 1.7 to 2.2 GHz (1.1 to 3.0 GHz for narrow band applications), the PE44820 is designed for optimising the transmission phase angle in wireless infrastructure and radar markets in applications such as antenna beamforming, distributed antenna systems (DAS) and phased-array antennas.
The PE44820 covers 358.6 degrees in 1.4-degree steps and has phase accuracy of Â±3 degrees. The phase shifter has RMS phase error of 1-degree and RMS amplitude error of 0.1dB. Linearity of 60dBm IIP3 ensures the phase shifter does not degrade the array transceiver's linearity, according to the company.
An integrated digital control interface supports serial and parallel programming of the phase setting. Built on Peregrine's UltraCMOS technology, the PE44820 has an extended temperature range up to 105degC and a supply range from 2.3 to 5.5V.
"The UltraCMOS PE44820 digital phase shifter demonstrates a core capability that Peregrine is now incorporating into fully integrated solutions such as our monolithic phase and amplitude controller (MPAC) product family," says Kinana Hussain, director of marketing at Peregrine Semiconductor. "This full-range digital phase shifter offers many advantages over discrete implementation. It is easy to design-in, requires little PCB space and has flexible programming."
Samples, evaluation kits and volume-production parts are available now.
