RF Digital Phase Shifter 8-bit, 1.7–2.2 GHz

The PE44820 is a HaRP™ technology-enhanced 8-bit digital phase shifter (DPS) designed for use in phased array and active antenna applications. This DPS covers a phase range of 358.6° in 1.4° 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 switch 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.
