Editing Tuned radio frequency receiver (section)

==Modern usage==
Although the TRF design has been largely superseded by the superheterodyne receiver, with the advent of semiconductor electronics in the 1960s the design was "resurrected" and used in some simple integrated radio receivers for hobbyist radio projects, kits, and low-end consumer products.   One example is the [[ZN414]] TRF radio [[integrated circuit]] from [[Ferranti]] in 1972 shown below
