What is RF ADC?
An RF sampling ADC can replace a radio signal path subsystem of mixers, LO synthesizers, intermediate frequency amplifiers and filters, and sometimes multiple ADCs, reducing bill of materials, cost, design time, size, weight, and power, while increasing the software programmability and flexibility of the system.
How do you convert RF signals to signals?
RF to IF conversion is achieved using a RF device called Down-converter. Heterodyne and homodyne receiver architectures are used to convert modulated RF signal to IF signal. Superheterodyne uses 10.7MHz as first IF and 470KHz as second IF.
What is a RF down converter?
an RF downconverter is a device which converts high radio frequency signal to low radio frequency signal is known as RF downconverter. Like RF upconverter, an RF downconverter will also have either one or two stages of mixing. Often RF downconverter is used in combination with RF LNA (Low Noise Amplifier).
What’s the difference between RF and IR?
RF (radio frequency) technology uses radio waves to transmit the audio signal. These are susceptible to RF interference. IR (infrared) technology uses infrared light to carry the audio signal thus keeping the signal in the room and eliminating RF interference.
How do RF mixers work?
A mixer takes an RF input signal at a frequency fRF, mixes it with a LO signal at a frequency fLO, and produces an IF output signal that consists of the sum and difference frequencies, fRF ± fLO.
How does an RF downconverter work?
Signals at the RF input port are mixed with signals at the LO port using a double-balanced mixer. These downconverter mixers operate with RF input frequencies between 400 MHz and 2,500 MHz, and downconvert to IF output frequencies between 10 and 500 MHz.
Is a device which convert digital data to analog?
The correct answer is Modem. Modem, (from “modulator/demodulator”), any of a class of electronic devices that convert digital data signals into modulated analog signals suitable for transmission over analog telecommunications circuits.
What is RF converter?
RF Converters: A Technology That Is Enabling Wideband Radios . This article takes a look at how RF converters can now deliver on the promise of wideband radios, dramatically reducing the hardware needed to create a radio, and enabling a new level of reconfigurability via software.
What is RF power output?
RF power measurements take many forms, depending on the RF transmitter design and application. The RF output may be a simple continuous wave (CW) signal, a pulse, an analog modulated signal, or a complex digitally modulated transmission, such as an IQ or orthogonal frequency division multiplexing (OFDM) waveform.
