Product Description
The PE44820 is a HaRP™ technology-enhanced 8-bit digital phase shifter (DPS) designed for use in a broad
range of applications including: beamforming networks, distributed antenna systems, active antenna systems
and phased array applications. This DPS covers a phase range of 358.6 degrees in 1.4 degree steps,
maintaining excellent phase and amplitude accuracy across the nominal frequency band of 1.7–2.2 GHz. The
PE44820 is also capable of extended frequency operation from 1.1–3.0 GHz for narrow band applications, as
detailed in Application Note 45. An integrated digital control interface supports both serial and parallel
programming of the phase setting. The PE44820 also features an external negative supply option for a faster
switching frequency, and is offered in a 32-lead 5 × 5 × 0.85 mm QFN package. In addition, no external blocking
capacitors are required if 0 VDC is present on the RF ports.
The PE44820 is manufactured on Peregrine’s UltraCMOS® process, a patented variation of silicon-on-insulator
(SOI) technology on a sapphire substrate.
Peregrine’s HaRP technology enhancements deliver high linearity and excellent harmonics performance. It is an
innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and
integration of conventional CMOS.
