This document describes the features and characteristics of Rev. N/D / Iss. 1 MODEL NO. DPS38017 3 Section Phase Shifter, including operating frequency, control type, insertion loss balance, isolation, phase shift range and accuracy, etc.
The DPS38017 3‑Section Phase Shifter from DAICO Industries provides precise phase shifting in 45° increments over a 0°‑315° range. It uses an ECL driver and includes an integrated power divider and amplifier for equal insertion loss.
Key performance figures include an operating frequency of 1243‑1253 MHz, typical insertion gain of 37 dB at 25 °C, isolation of 20 dB between ports, and a switching speed of about 2 seconds. The device operates from ±5.2 V to +15 V supplies and draws low DC current (65 mA at +15 V).
