Abstract
1,188,912. Radio receiving circuits. UNITED STATES ATOMIC ENERGY COMMISSION. 14 Oct., 1968 [7 Nov., 1967], No. 48491/68. Heading H3Q. [Also in Division H1] An aerial 16 is coupled to a receiver through a resonant cavity 10 containing an ionized gas. The gas is ionized by means of R.F. energy fed from a klystron 22 through a coupling loop 20. It is stated that the resonant frequency depends upon the frequency of the excitation energy (see Division H1), whereby the klystron may be used as a remote turning means for the cavity.
