TL;DR: In this article, a broadband high frequency balun is connectable between balanced and unbalanced transmission lines so that these lines are essentially colinear, and the addition of a lossy layer to the inner surface of the housing permits a substantial increase in the operating bandwidth of the balun by suppressing adverse resonance effects within the housing.
Abstract: A broadband high frequency balun is connectable between balanced and unbalanced transmission lines so that these lines are essentially colinear. The balun comprises a coaxial cable and a shorted stub in approximately a half-loop configuration, the balanced line being connected to the cable and stub within a conductive housing or shield. The cable-stub spacing is substantially greater than the effective length of the stub, thereby decreasing the lower frequency operating limit of the balun. The addition of a lossy layer to the inner surface of the housing permits a substantial increase in the operating bandwidth of the balun by suppressing adverse resonance effects within the housing.

TL;DR: In this paper, the impedance measurement of small, microwave lumped elements of the order of 1 mm has been extended up to 12 GHz by a technique in which the frequency and Q of a resonant transmission line are perturbed by the connection of a lumped element.
Abstract: The impedance measurement of small, microwave lumped elements of the order of 1 mm has been extended up to 12 GHz by a technique in which the frequency and Q of a resonant transmission line are perturbed by the connection of a lumped element. With the use of low-loss resonant coaxial lines, the technique has been applied to the measurement of lumped-element capacitors ranging from 0.4 to 3.6 pF and inductors ranging from 1.1 to 4.3 nH. Conductor Q values for capacitors as high as 1700 at 1.4 GHz and 100 at 12 GHz have been measured and estimates of dielectric Q values for capacitors of over 5000 have been obtained. Single-turn 1.1-nH inductor Q's of 40 at 1 GHz and 90 at 7 GHz have also been measured. The capacitors and single-turn inductors are found to have constant C and L values up to 12 GHz.

TL;DR: In this paper, a second harmonic filter for a doppler radar intrusion system or the like is presented, which includes a cavitiy with an elongated coupling port containing an active device for generating microwave energy which is radiated through the cavity through the coupling port.
Abstract: A second harmonic filter for a doppler radar intrusion system or the like which includes a cavitiy with an elongated coupling port containing an active device for generating microwave energy which is radiated through the cavity through the coupling port. In one embodiment the second harmonic filter includes a dielectric sheet which bridges the coupling port and which supports a resonant tuning stab. The resonant tuning stub is positioned orthogonal to the elongated dimension of the coupling port and is spaced from the coupling port. The tuning stub forms a capacitor with the coupling port and is dimensioned so as to resonate at the second harmonic frequency to act as a band stop filter at that frequency. In a second embodiment, the elongated coupling port includes a pair of opposed projections positioned mid-way between the ends of the port to form a pair of inductors and a capacitor between them which acts as a band stop filter at the second harmonic frequency.

TL;DR: An ultrasonic/electrical transducer for operation at a given frequency in an ultrasonic intruder alarm system is provided with a shallow self-supporting dish-shaped radiator mounted at the center of its concave surface to one face of a piezoelectric ceramic crystal as mentioned in this paper.
Abstract: An ultrasonic/electrical transducer for operation at a given frequency in an ultrasonic intruder alarm system is provided with a shallow self-supporting dish-shaped radiator mounted at the center of its concave surface to one face of a piezoelectric ceramic crystal. The opposite face of the crystal is secured to one end of a tuning stub which extends one-half wavelength from the center of the radiator and is connected at its midpoint to a base through an accoustic isolator. The stub is tuned by addition of trimming washes to its free end. The crystal is of the expansion/compression type having its piezoelectric axis parallel to that of the tuning stub and perpendicular to the surface of the radiator. The base is made of two parts joined by means which are the structurally weakest point of the assembly so that, if the transducer is tampered with, this point will move tripping a tamper switch to signal the alarm.

Abstract: A lateral pipeline being laid is connected to a main pipeline lying on the bottom of the ocean by a tie-in assembly that is connected to the lateral line above the surface of the water. The main line is equipped with a stub section of pipeline to which the lateral is to be connected. The angle between the lateral and the main line is measured and from this the tie-in assembly is designed. This assembly also includes two ball and socket type joints that permit limited misalignment between the sections of the tie-in assembly and the stub section of the pipeline connected to the main line and also allows relative rotation between at least two portions of the tie-in assembly. A connector assembly is used to connect the tie-in assembly to the stub pipeline section. An actuator is releasably connected to the tie-in assembly above the surface of the water and lowered with the tie-in assembly into the water to actuate the connector assembly to connect the tie-in assembly and the stub pipeline section. This actuator can then be recovered and used again.

29 Feb 1972TL;DR: In this article, an agile microwave phase shifter of the loaded line type using ferrite material as the active element is presented, which is fabricated in the shape of an annulus and disposed in a radial cavity which encircles and terminates a coaxial stub attached to a main coaxial transmission line.
Abstract: An agile microwave phase shifter of the loaded line type using ferrite material as the active element. The active ferrite material is fabricated in the shape of an annulus and is disposed in a radial cavity which encircles and terminates a coaxial stub attached to a main coaxial transmission line. The ferrite annulus may be operated between states of magnetization that are either below or above the high-loss resonance region. To achieve low magnetization energy, short switching time, and low losses in signal power, the ferrite annulus is made very thin so that its internal magnetic field is substantially uniform and the total magnetomotive force required to produce a given field is small.
