Basics of SAR and ISAR Radar – Radar Operation – Part 4 Synthetic aperture radar (SAR) and inverse SAR (ISAR) are methods of using radar to map a stationary object, more usually terrain. SAR/ISAR systems are deployed on aircraft or satellites that move at high velocities in respect to the surface of the earth or...

Pasternack Introduces New Line of In Stock Bi-Phase Modulators Operating in Frequency Bands from 0.5 to 40 GHz New TTL-Controlled Bi-Phase Modulators are Ideal for Encoding the RF Carrier Using 2 Phase Shift Keying (2PSK) IRVINE, Calif.  – Pasternack, an Infinite Electronics brand and a leading provider of RF, microwave and millimeter wave products, has...

Double Ridge Waveguide Versus Typical Waveguide June 25, 2020 By: Peter McNeil Like all waveguides, ridged waveguides carry electromagnetic radiation in the form of a transverse wave. The fundamental mode of most waveguides used in interconnect and RF devices is the transverse electric (TE) mode with no electric field in the direction of propagation. This means...

How are End-launch, PCB Connectors Useful? There has been an increasing use of RF coaxial connectors, especially microwave and millimeter-wave coaxial connectors, for high-speed digital and precision sensing applications, There are also a growing trend toward highly compact and interconnect dense microwave and millimeter-wave systems, such as multi-input multi-output (MIMO) antennas for 5G and actively...

Waveguide Amplifier Introduction & Applications Waveguide amplifiers, or full-band/multi-band waveguide amplifiers, are amplifiers housed in assemblies that have either waveguide or coaxial interconnect. Though waveguide interconnect is more common for waveguide amplifiers, some waveguide amplifiers have coaxial interconnect instead, but still perform as specified over a given waveguide frequency band. The main feature of waveguide...
