Software-defined radio (SDR) provides a reusable—and, to some extent, “future proof”—radio platform utilizing an RF to baseband transceiver and digital processor architecture. SDR can improve system performance, reduce system size, and minimize design

Jan 5, 2014 · If you want an SDR with 50 MHz bandwidth, you can do that with a single 100 MHz ADC as you describe, or two 50 MHz ADCs and I/Q sampling. Either way, it's 100 million samples per second, so the ADC complexity is essentially the same.

Sep 24, 2019 · The ADC is the bridge between the analog and digital in the world of SDR. It is in fact a key component of SDR. The output of an ADC is a string of ones and zeros that vary with the incoming signal. This string can be processed by a Field Programmable Gate Array (FPGA) or a microprocessor.

Jun 30, 2020 · By digitizing the radio signals directly using an appropriate analog-to-digital converter (ADC), an SDR can implement all these functions in software so that the same hardware is used for multiple radio modes, whether AM, FM, CW, single sideband (SSB), or double sideband (DSB).

Web-888 SDR inherits the robust RF and ADC design from RX-888, featuring a 16-bit ADC with a tunable sampling rate for superior signal fidelity. Covering a spectrum from 1kHz to 62MHz and VHF range from 118MHz to 150MHz, the Web-888 SDR ensures comprehensive signal reception for diverse applications.

TRX-duo is an SDR device that supports dual-channel physical reception and transmission. It utilizes 2 x 16Bit ADC LTC2208 for the direct sampling of the 10KHz-60MHz RF signal. It features with high dynamic range, high sensitivity, and high feasibility of remote deployment(operation).

Analog-to-Digital Converter (ADC): After the RF front end, the analog signal is digitized. The ADC takes a continuous analog voltage (the RF or IF signal) and converts it into a stream of digital numbers (samples).

A Software Defined Radio (SDR) is a radio where digitizing the signal allows circuitry previously implemented in dedicated hardware to be moved into the digital domain. Ideally, an ADC could directly sample the signal from the antenna.

Oct 2, 2007 · digital-to-analog data converters for Software-Defined Radio (SDR) applications. It also explains how ADS61xx ADCs and the DAC5688 from Texas Instruments fit properly for SDR designs. Contents 1 Introduction to Software-Defined Radio..... 2

Nov 1, 2014 · The dynamic range of the ADC is the fundamental trade-off between analog and digital filtering. More analog filtering reduces the amplitudes of the interferers and the required range of the ADC, which must digitize both the desired signal and interferers to maintain a …
