Title: Ultra-high frequency multi-section tuner
IPC: H03H7/01
Filed: 1955-01-25
Abstract: 763,918. Resonators. OAK MFG. CO. Jan. 25, 1955 [Jan. 25, 1954], No. 2207/55. Class 40 (8). A tuning system comprises at least two quarter-wave coaxial type cavities coupled by means of slots in the common partition wall or walls. The tuner shown has two sections 132, 133 having axial conductors 145, 146 of rectangular cross-section rigidly joined to the end wall 115 of the assembly. Coupling at the highfrequency end of the range is provided by a slot 160, Fig. 10, in the common wall 126 between the cavities near the low potential end of the axial conductors. Adjustment of the coupling may be effected by means of a bolt 162 which engages the edges of the slot 160. An alternative form of adjustment consists in a metallic bridge which is slidable along the slot. At the low-frequency end of the range coupling is effected by means of one or (as shown) two partcircular slots 167, 168. The degree of coupling is adjusted by means of a pivoted bridge 170 of metal. The cavities are tuned by means of two pairs of vanes 137 arranged in capacitative relation with the ends of the axial conductors. The vanes are arranged on a common shaft 130 which carries radially extending wipers 140 making contact with the walls of the cavities. Radial slots (not shown) in the vanes enable portions of them to be bent transversely in order to secure desired tracking characteristics. The shaft 130 and vanes 137 may form a detachable unit, the side walls 112, 113 of the tuner being slotted to enable the unit to be withdrawn. The cover-plate 188 of the cavities extends inwardly the full length of the axial conductors 145, 146. It is provided with adjustable metallic tuning fingers 190. Energy is introduced into the cavities from an aerial circuit by means of a pair of loops 150 which lie just above and to either side of the axial conductor 145. A further cavity 134, Figs. 3 and 9, serves as the tank circuit of a local oscillator and is not directly coupled to the first two sections 132, 133. Axial conductor 175 is supported on an insulating block 180 and is provided with a terminal 182 for connection to a triode oscillator. Energy is coupled to a diode mixer circuit by means of a resistive pick-up inductor 34. Trimming capacitors 184, 185 for the high- and low-frequency ends of the range are carried by bolts tapped into the side 112 of the tuner.
