A coaxial attenuator is an energy-degrading RF/microwave component that contains resistive materials inside. In addition to the commonly used resistive fixed attenuators, there are also electronically controlled fast-adjustment attenuators.Attenuators are widely used in a variety of applications where power level adjustment is required. The basic materials that make up a coaxial attenuator ar……

Lumped-parameter design and Distributed-parameter design are common methods of radio frequency circuit design. This article will introduce the characteristics and differences between the two briefly. Feature summaryLumped circuit theory: circuit size is much smaller than the wavelength.Distributed Circuit Theory: circuit size is comparable to wavelength. Lumped parameter circuitLumped pa……

The Q band is a range of frequencies contained in the microwave region of the electromagnetic spectrum. Common usage places this range between 33 and 50 GHz, but it may vary in term of sourcing. The Q band is in the EHF range of the radio spectrum. The Q band is mainly used for satellite communications, terrestrial microwave communications and for radio astronomy studies such as the QUIET tel……

The reverse power (or reflected power) is the sum of all the power output from the device to the capacitor plate or the inductor coil, including the effective power absorbed by the load and the reflected power not absorbed. Usually recorded as Pr. The measurement of reverse power is an important part of network measurement. For RF signals, reflections occur when the impedances of two connecte……

In this article, we are going to introduce the DBS band from five points.The definition of DBS, how it is transmitted, how it features, how it develops, & satellite frequency bands. Definition: DBS, or Direct Broadcasting Satellite Service, usually refers to the use of geosynchronous orbit satellites to radiate a certain area on the ground with high power, and transmit information such as……
