QPC2108

Overview

The Qorvo QPC2108 is a packaged 6-bit digital phase shifter fabricated on a high-performance 0.15 um GaAs pHEMT process. It operates over a frequency range of 2.5 to 4 GHz with bi-directional signal capability and 360° coverage, where the least significant bit (LSB) equals 5.625°. Key electrical parameters include an RMS phase error of less than 2.8° from 2.5–3.8 GHz and less than 5° from 3.9–4 GHz, alongside an RMS amplitude error under 0.4 dB. The device exhibits an insertion loss of 5 dB, return loss of 16 dB, input P0.1dB of 23 dBm, and input IP3 of 45 dBm. Switching speed is under 100 ns with control voltages of 0/+5 V. It is housed in a 6.0 x 6.0 x 0.79 mm QFN package.
