US Patent:

40706273, Jan 24, 1978

Filed:

Jun 3, 1976

Appl. No.:

5/692547

Inventors:

Joseph Richard Jasinski - Shillington PA
James Bruce Pickard - Quincy IL
Claude Edward Doner - New Providence PA

Assignee:

RCA Corporation - New York NY

International Classification:

H04B 104
H04N 514
H04N 538
H03F 360

US Classification:

325127

Abstract:

A substantially constant impedance is developed across the input terminals of a linear amplifier used in a very high frequency (VHF) low band television transmitter. The input circuit consists of lumped components arranged in a capacitively coupled double tuned configuration. A relatively long coaxial transmission line system is used to connect the input circuit to the terminals of the tube. The coaxial line system and input circuit tunes across the entire VHF low band of 54 to 88 MHz. An input voltage standing wave ratio (VSWR) equal to or less than 1. 2:1 is achieved over each six MHz channel.

Assignee:

RCA Corporation - New York NY

International Classification:

H01P 704

US Classification:

333224

Abstract:

A transmission line cavity comprises an outer conductor and a center conductor. The cavity is in combination with a source, such as a power tube, for establishing electromagnetic waves within the cavity. The impedance of the center conductor may be changed, for example by changing the series inductance, to vary the resonant frequency of the cavity.

Appl. No.:

Assignee:

RCA Corporation - New York NY

International Classification:

H03F 360
H01P 704

US Classification:

330 56

Abstract:

Coaxial, one-quarter wavelength resonant primary and secondary resonators are employed in conjunction with a tetrode tube to provide, for example, 55 Kw (kilowatts) of output power for VHF, high-band television broadcasting. Coupling between the two resonators is accomplished by connecting an inductance between the center conductors of the resonators. The effective inductance of this connection is varied (and thus the coupling of the resonator circuits is also varied) by the addition of a variable capacitor in series with the inductive connection.

International Classification:

H01J 146
H01J 2110

US Classification:

313293

Abstract:

An improved high power electron tube has at least one grid electrode. The grid electrode is formed from a one piece cylindrical member, closed at one end, having an outside diameter, D. The cylindrical member has a plurality of arcuate, circumferentially elongated apertures extending therethrough. Each of the apertures has a length x and a width y wherein the length x is greater than width y, and wherein the length x is not greater than 0. 55 times the diameter, D, of the electrode. The width y, of each of the apertures is not greater than 0. 1 times the diameter D, of the electrode.
