Radio Frequency Integrated Circuits (RFICs) are essential components ... Wideband receivers are also a focus of current research, with efforts to balance noise performance and linearity.

The aim of this paper is to study and design a voltage doubler circuit (Figure 1) for the RF energy harvesting using 28 nm FD-SOI ... dynamic resistance and leakage current which will be explained in ...

you’ll see there is a lot of difference between active audio filters and passive RF filters, although some of the ideas are the same. Watching the effect different circuit tweaks have in real ...

and that requires a special circuit that will block high-power signals while passing low-level signals. Because of the low level of signals involved, you do need some special RF techniques.
