“…After the values of u avg and u τ are substituted into (11), we obtain u pk =4%, which means that the actual peak power is believed to lie in the interval 22.3±0.9 W with a level of confidence of approximately 68.3%. Although some very conservative assumptions have been made, it can be seen that the peak power uncertainty is well controlled.…”

This paper presents the analysis and design of a new W-band pulsed transmitter using injection-locking to achieve pulse-to-pulse coherence and power amplification. First, a new timing scheme is introduced to solve the asynchronous problem that commonly exists in multistage injection-locked transmitters. Then the pulsewidth of one stage in the transmitter is intentionally made somewhat longer than that of the next stage, and thus, the rising edge noise of the output pulse is minimized. Finally, a high coherent peak power can be achieved without using complex power combing techniques. To verify our analysis, a W-band pulse transmitter is designed and fabricated that operates at a 78 ns pulsewidth, 50 µs pulse period, and 600 MHz locking bandwidth. The experiment shows that a coherent peak power of 22.3±0.9 W was achieved at 94.2 GHz.

“…In the U.S.A. during the past 3 years, baseband and RF pulse measurement techniques have undergone rapid development. Central to this development has been the implementation and refinement of sampling techniques in (1) RF pulse power measurements, (2) baseband pulse peak voltage measurements, and (3) baseband pulse time-domain measurements [Hudson, 1967;Ondrejka, 1967;Nahman, 1967].…”
