The performance of a millimetre‐wave wavelet generator under picosecond‐pulsed trigger operation conditions has been evaluated experimentally. The reactively‐loaded resonant tunnelling diodes metal–oxide‐semiconductor field‐effect‐transistor circuit is shown to generate well‐formed wavelets for control pulse‐lengths down to approximately the free‐running carrier oscillation period. Transient circuit simulations have also been implemented to provide additional insight into the observed circuit dynamics. [ABSTRACT FROM AUTHOR]

An ultra-wideband, non-dispersive leaky lens antenna system for impulse applications has been designed, fabricated and characterised. An in-house wavelet generator is connected to the antenna to transmit 100 ps-long square pulses with centre frequencies at 45, 60 and 75 GHz. It is shown that the leaky lens antenna has negligible distortion and preserves the pulse shape generated by the millimetre-wave pulse generator. [ABSTRACT FROM AUTHOR]
