SR connector (from Russian: Cоединитель Pадиочастотный) is a Russian RF connector, based on the BNC connector and which comes in a 50 Ω and 75 Ω versions; TNC connector (threaded Neill-Concelman) Twin-BNC (Twinax) Twinax connectors are used with 78 Ω or 95 Ω conductor cables and operate from 0–200 MHz. Due to ...
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.
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target.
An RF receiver module receives the modulated RF signal, and demodulates it. There are two types of RF receiver modules: superheterodyne receivers and superregenerative receivers. Superregenerative modules are usually low cost and low power designs using a series of amplifiers to extract modulated data from a carrier wave.
Like other electrical switches, RF and microwave switches provide different configurations for many different applications. Below is a list of typical switch configurations and usage: Single pole, double throw (SPDT or 1:2) switches route signals from one input to two output paths. Single pole double throw (SPDT) switch from Agilent Technologies
The RFID Network responded to these fears in the first episode of their syndicated cable TV series, saying that they are unfounded, and let RF engineers demonstrate how RFID works. [147] They provided images of RF engineers driving an RFID-enabled van around a building and trying to take an inventory of items inside.
Some form of encoding is used in the signal so that the missile can steer itself into the center of the beam. Changing frequencies or dot patterns are also commonly used. These systems have the advantage that the link between the launcher and missile cannot easily be broken or jammed.
Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.
