and tunable/dither magnetrons, together with a capability for varying the
excursion, rate and tuning waveform.
Figure 12.55 illustrates the agile rate and agile excursion of a typical X-band
frequency–agile coaxial magnetron with pulse voltage 15 kV, pulse current
15 A, maximum duty cycle 0.0011 accutune range 1 GHz, centre frequency
9.10 GHz and peak power 90 kW.
This gure leads to the following denitions:
Agile rate is the number of times per second that the transmitter fre-
quency traverses the agile excursion and returns to its starting
frequency.
Agile excursion is the total frequency variation of the transmitter duri ...
