Introduction to RF & Wireless Communications Systems
WEBOct 13, 2017 · RF itself has become synonymous with wireless and high-frequency signals, describing anything from AM radio between 535 kHz and 1605 kHz to computer local area networks (LANs) at 2.4 GHz. However, RF has traditionally defined frequencies from a few kHz to roughly 1 GHz. If one considers microwave frequencies as RF, this range extends to …
Learn About Circulators and Isolators | Microwaves & RF
WEBAug 20, 2016 · Circulators and isolators are three-port passive electronic devices that help direct the flow of microwave signals in RF equipment and systems. A port is defined as a connection point for either an input signal, output signal, or termination. Figure 1a shows the standard schematic symbol for a circulator. The arrow indicates the unidirectional ...

The Critical Role OTA Testing Will Play in 5G - Microwaves & RF
WEBMar 1, 2019 · OTA Overview. As 5G mobile technology evolves to millimeter-wave (mmWave) frequencies of 28 GHz, 39 GHz, and beyond, several drivers will necessitate OTA testing. At mmWave frequencies, signal-absorption rates are much higher, requiring the need for directional transmissions/reception (beam focusing or …
A Brief Tutorial on Microstrip Antennas (Part 1)
WEBNov 6, 2018 · In a properly designed microstrip antenna, the radiation intensity is in a direction normal to the radiating element (i.e., broadside). For the rectangular microstrip antenna, the length, L, is typically one-third to one-half wavelength long, depending on the substrate relative dielectric constant, which is commonly 2.0 to 10.0.The lower values of dielectric constant yield higher efficiency.
Comparing Narrowband and Wideband Channels - Microwaves & RF
WEBFeb 7, 2018 · In short, wideband channels can carry more information than narrowband channels, but they typically require more power to do so. Narrowband channels typically carry much less information than wideband channels and operate over shorter distances between transmitter and receiver. But because narrowband channels have less noise and typically lower ...
