A 6 GHz quadrature active microwave phase shifter employing single‐gate packaged MESFETs is practically evaluated. A continuous phase change over the range of 50° and 3 dB gain with ±0.7 dB variation are demonstrated. The circuit is simple, and its performance makes it ideal for feedforward systems applications. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 15: 359–360, 1997.
