There are six main challenges when designing a custom RF/Microwave Switch Matrix from beginning to end: Mechanical Design: design of an electrically shielded enclosure or box, internal component mounting brackets, with a component and cabling layout. RF/Microwave Design: a signal routing and signal conditioning design and testing plan. A ...
The prior art includes an RF MEMS frequency tunable fractal antenna for the 0.1–6 GHz frequency range, [18] and the actual integration of RF MEMS switches on a self-similar Sierpinski gasket antenna to increase its number of resonant frequencies, extending its range to 8 GHz, 14 GHz and 25 GHz, [19] [20] an RF MEMS radiation pattern ...
Advanced Design System (ADS) is an electronic design automation software system produced by PathWave Design, a division of Keysight Technologies. [1] It provides an integrated design environment to designers of RF electronic products such as mobile phones, [2] pagers, wireless networks, satellite communications, radar systems, and high-speed data links.
The antenna elements fed by a Butler matrix are typically horn antennae at the microwave frequencies at which Butler matrices are usually used. [4] Horns have limited bandwidth and more complex antennae may be used if more than an octave is required. [5]
QSK operation is a technical challenge: It requires very fast T/R RF switches at the high power and voltage side of the radio transceiver. Such switches must be controlled automatically by the telegraph key, and as such they must be rapid enough to be perceptually undetectable by the telegraph operator.

Basic automatic frequency control in a radio receiver. У = RF amplifier stages, Д = frequency discriminator stage. In radio equipment, Automatic Frequency Control (AFC), also called Automatic Fine Tuning (AFT), is a method or circuit to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal.
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
