Module physical connection: land grid array, through-hole, and castellated boardlet (from left to right) A variety of methods are used to attach an RF module to a printed circuit board, either with through-hole technology or surface-mount technology. Through-hole technology allows the module to be inserted or removed without soldering.
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 ...
Series PDM modulators are used in solid state transmitters also, but the circuits are somewhat more complex, using push pull or bridge circuits for the RF section. These simplified diagrams omit such details as filament, screen and grid bias supplies, and the screen and cathode connections to RF ground.
Block diagram of a superheterodyne receiver. The RF front end consists of the components on the left colored red. In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. [1]
An 802.15.4 radio module is a small device used to communicate wirelessly with other devices according to the IEEE 802.15.4 protocol. This table lists production ready-to-use certified modules only, not radio chips. A ready-to-use module is a complete system with a transceiver, and optionally an MCU and antenna on a printed
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
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 a radio antenna, the feed line (feedline), or feeder, is the cable or other transmission line that connects the antenna with the radio transmitter or receiver.In a transmitting antenna, it feeds the radio frequency (RF) current from the transmitter to the antenna, where the energy in the current is radiated as radio waves.
