  2. RF module - Wikipedia

    en.wikipedia.org/wiki/RF_module

    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.

  3. Universal Software Radio Peripheral - Wikipedia

    en.wikipedia.org/wiki/Universal_Software_Radio...

    Several classes of daughterboard modules exist: Receivers, Transmitters and Transceivers. Transmitter daughterboard modules can modulate an output signal to a higher frequency; Receiver daughterboard modules can acquire an RF signal and convert it to baseband; Transceiver daughterboard modules combine the functionality of a Transmitter and ...

  4. Radio transmitter design - Wikipedia

    en.wikipedia.org/wiki/Radio_transmitter_design

    A radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. Radio waves are electromagnetic waves with frequencies between about 30 Hz and 300 GHz. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the ...

  5. Transmitter - Wikipedia

    en.wikipedia.org/wiki/Transmitter

    Commercial FM broadcasting transmitter at radio station WDET-FM, Wayne State University, Detroit, US.It broadcasts at 101.9 MHz with a radiated power of 48 kW.. In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal ...

  6. RF power amplifier - Wikipedia

    en.wikipedia.org/wiki/RF_power_amplifier

    The transmitterreceivers are used not only for voice and data communication but also for weather sensing (in the form of a radar). [9] RF power amplifiers using LDMOS (laterally diffused MOSFET) are the most widely used power semiconductor devices in wireless telecommunication networks, particularly mobile networks.

  7. Radio-frequency microelectromechanical system - Wikipedia

    The prior art includes an RF MEMS frequency tunable fractal antenna for the 0.1–6 GHz frequency range, [18] and the actual integration of RF MEMS switches on a self-similar Sierpinski gasket antenna to increase its number of resonant frequencies, extending its range to 8 GHz, 14 GHz and 25 GHz, [19] [20] an RF MEMS radiation pattern ...

  8. RF chain - Wikipedia

    en.wikipedia.org/wiki/RF_Chain

    An RF chain is a cascade of electronic components and sub-units which may include amplifiers, filters, mixers, attenuators and detectors. [1] It can take many forms, for example, as a wide-band receiver-detector for electronic warfare (EW) applications, as a tunable narrow-band receiver for communications purposes, as a repeater in signal distribution systems, or as an amplifier and up ...

  9. Wireless keyboard - Wikipedia

    en.wikipedia.org/wiki/Wireless_keyboard

    A wireless keyboard can be connected using RF technology with the help of two parts, a transmitter and a receiver. The radio transmitter is inside the wireless keyboard. The radio receiver plugs into a keyboard port or USB port. Once the receiver and transmitter are plugged in, the computer recognizes the keyboard and mouse as if they were ...
