Microwave/RF components are used by military and commercial end users. A company which specializes in this industry provides these components and manufactures them as well. The firm also offers electro-mechanical and pin diode based switching products, defense technology solutions and pin diode based limiters for pulsed power up to 600 Watts. The list of manufactured equipments includes passive components such as couplers, power dividers, terminators, attenuators, detectors, adapters and phase shifters. An rf phase shifter is a device that alters the phase angle of a microwave signal. In other words, this equipment, used in measuring, automation and conversion technology, changes the stage of electromagnetic oscillations. The design of a phase shifter depends on the limits of phase change, accuracy of the equipment and the range of operating frequencies. This passive component can be controlled magnetically, electrically and mechanically. Phase shifter circuits are used in several radio frequency applications namely phased array antenna systems and modulators as they create a phase difference between input and output signals resulting in the formation of electrical beams. This microwave component is utilized to obtain high switching rate, reciprocity, reliability, miniaturization and weight reduction. A radio frequency (rf) signal detector traces the hidden information sent in the form of a modulated wave. It detects the presence of privacy invading bugs in the area or room and generates a warning message to tell about the active RF transmitters. The output shown by this instrument represents the wave difference between two oscillating input signals. To work at radio frequencies at the multi-megahertz range, coaxial connectors are used. This connector is attached to the end of a coaxial cable which carries rf signals. There are many types of connectors, which are used nowadays. They are N-type, BNC, TNC and SMA connectors. When it comes to SMA or subminiature A connector, this kind of component is commonly used in microwaves or radio waves. It is designed to connect at a frequency of 12 GHz, however; a quality SMA can carry a frequency up to 18 GHz. Other equipments which are used in RF systems are adapters, which convert the transmitted data from one presentation form to another. Attenuators reduce the amplitude of an electronic signal and power dividers split the power and combine it when used in reverse. The directional couplers merge a defined amount of electromagnetic power in a transmission line enabling the signal to be used in another circuit.
