A proof-of-concept analogue reflection-type time shifter is presented for the first time. The measured results for an experimental hybrid realisation, having a centre frequency of 750 MHz, demonstrate a high performance over a 40% bandwidth. The design is totally compatible with monolithic technology and suitable for both microwave and millimetre wave applications.
