The small signal impedance of GaAs/Al(Ga)As doublebarrier resonant tunnel diodes has been measured and analysed over a wide range of frequencies and for various DC bias values. A method is introduced to evaluate the equivalent circuit parameters, the cut-off frequency and the self-resonant frequency. This also yields intrinsic values of R, Rs, C and L associated with the device structure.
