SUPPRESSION OF SPURIOUS FREQUENCIES

Abstract

The research described in this report covers several aspects of the fight to suppress the emission of spurious energy from high-power transmitters: waffle-iron filters to provide high reactive attenuation; harmonic pads to protect the transmitter and prevent arcing from harmonic resonance; leaky-wave filters to provide high dissipative attenuation; band-stop filters to provide high attenuation at particular frequencies; and wide-band bolometers to measure the combined power of many harmonic frequencies. The analytical investigation included the effect of filter bandwidth and filter type on the attenuation and group delay, and on the transient response to both rectangular and shaped pulses.
