THE WAVEGUIDE TUNNEL DIODE AMPLIFIER: DESIGN CONSIDERATIONS.
Abstract
An analytic design procedure for waveguide tunnel diode amplifiers based on the use of commercially available packaged tunnel diodes and the manufacturer furnished specifications for these devices is outlined. This approach is found to be inadequate for the realization of an amplifier that must meet specified performance criteria. However, the waveguide structure resulting from this design procedure should be suitable for performing microwave frequency measurements that will allow a more complete characterization of the waveguide tunnel diode network and therefore a more exact design procedure. The extreme fragility of high resistive cutoff frequency tunnel diodes requires that extreme care be used in the mounting and biasing of these devices. Pressure- and shock-absorbing devices should be used in the mounting structure to avoid destruction of the tunnel diode. It is concluded that the realization of tunnel diode amplifiers for frequencies above 26 GHz will necessitate new packaging techniques and possibly even new fabrication techniques for the tunnel diode itself.
