Hi everyone,
I want to built a bidirectional amplifier for Wi-Fi and i'm looking for design schematic to do that.
Thank you for your help
regards
Interesting design I came across recently: "Reconfigurable Dual Band Bidirectional Reflection Amplifier with Applications in Van Atta Array"
paper1: https://ffarza2.people.uic.edu/RF_Circuits.html#Van
paper2: https://www.semanticscholar.org/pap...Chen/e3189616dfea9257864d91ea20ff9328fe476700

It may be constructed using two FET transistors and microstrip quadrature hybrid coupler.
FET reflection-type amplifiers are often used for series-feedback oscillators (design procedures could be found in many sources). For bidirectional amplifier application we must minimize reflections from hybrid.
Yeah, that would also have been my second suggestion ;-)
i found this , https://www.qsl.net/n9zia/wireless/2.4amp-rfsense.html , and this is the same i wanted to do .
what do you think about ?
