PREFERRED-CIRCUIT TECHNIQUES FOR TUNNEL-DIODE AMPLIFIERS.
Abstract
This report describes an investigation of radio frequency interence (RFI) in tunnel-diode amplifiers. Equations are derived which predict the harmonic and intermodulation power levels, or rejection of harmonics and intermodulation, and the percent cross-modulation as a function of tunnel-diode and circuit parameters. The parameters that must be known to make use of the equations are the diode peak voltage and current, bias voltage, source impedance, and amplifier gain. A push-pull, tunnel-diode amplifier was developed to demonstrate the feasibility and the advantages of a balanced amplifier. Measurements were made of the significant intermodulation and cross-modulation interference effects and then compared with the predicted effects. The results agreed with the theoretical predictions.
