The AN/URM-25 was part of a series of vacuum tube-based signal generators built for the U.S. military in the early Cold War-era.. Today they are collected and used by vintage amateur radio and antique radio enthusiasts who say they provide reasonably high accuracy and stability for a low cost, with build quality reflecting tough military construction requirements and standards.
It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT. The software code is now open source and is developed by a small team.
The Numerical Electromagnetics Code, or NEC, is a popular antenna modeling computer program for wire and surface antennas. It was originally written in FORTRAN during the 1970s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory. The code was made publicly available for general use and has subsequently been ...
The AN/PRC-160 began production in 2017 as the HF manpack component to the Harris Falcon III ecosystem of tactical radios. [4] Several DoD contracts have since been signed by branches of the US military, including a nearly $8 million US Air Force contract for 264 radios. [5]
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.
A radio-frequency integrated circuit, or RFIC, is an electrical integrated circuit operating in a frequency range suitable for wireless transmission. Applications for RFICs include radar and communications.
In telecommunications and radar engineering, the antenna boresight is the axis of maximum gain (maximum radiated power) of a directional antenna.For most antennas the boresight is the axis of symmetry of the antenna.
RF Engines Limited of Newport, Isle of Wight, UK was founded in 1999. RF Engines ( RFEL ) develops products based on high performance, digital signal processing techniques that enable fast moving events or fleeting, hopping signals occurring in the radio spectrum to be identified and acquired in real-time for subsequent analysis.
