Jack Browne Technical Contributor Microwaves & RF Magazine Coaxial cable assemblies are indispensable, signal-routing components in many RF/microwave systems, although they are often specified and added as an afterthought….

Courtesy of Pasternack : Types of Antennas at the RF and Microwave Frequency Monopole The monopole is a resonant antenna and the length of the antenna is determined by the wavelength of the radio waves being received and transmitted. A monopole antenna is usually made of a single conductor mounted over the ground with one side…

Courtesy of Pasternack : Antenna Performance Criteria Part 2 Antennas are essential components of RF and microwave devices and are used in a wide variety of applications including radio and television broadcasting, radar, cellular transmission, and satellite communications to name a few. Antennas are designed to transmit and receive radio waves determined by the design of…

Courtesy of Pasternack : Antenna Performance Criteria RF Antennas Antennas are used to channel radio waves for the purpose of communicating information across distances without wires. Antennas are necessary for a radio receiver or transmitter to convey signals between, for example, radio and television broadcast, cellular networks, Wi-Fi devices, radar and GPS, and remote control devices….

Courtesy of Pasternack Blog : Coaxial Cable Loss due to Loss Tangent Electrical losses in a coaxial cable create heat in the outer and center conductors and are the two main types of coaxial cable loss, skin-effect loss and dielectric loss, respectively. This heat, or loss, can be calculated with the understanding of the following concepts. What…

Courtesy of Pasternack : Coaxial Cable Loss due to Dielectric Conduction The coaxial cable provides a transmission line with low loss characteristics that can shield from outside signals and provide a durable yet flexible line that can be used in a variety of applications with a wide range of frequencies.  At microwave frequencies, much of the…
