Abstract :
A resonant-cavity filter has been developed which is tunable over the range 7.9¿11.0 cm. It is terminated in an R.A.E. plug and socket and has a second-harmonic rejection of greater than 30 dB. The insertion loss is of the order of 0.2 dB, and the voltage standing-wave ratio is better than 0.8 when measured in 71-ohm coaxial line.
