Application Brief RF signal sources are used to create test waveforms at radio frequency frequencies. Some common applications include: testing whether a new radio platform can work, or testing whether the performance of a mobile phone off the production line meets expectations. RF signal sources can be used to create simple waveforms such as sine waves, as well as complex modulation waveforms that look like echoes from ultrasound or sonar equipment. System design considerations and main challenges With the continuous innovation of technology, the frequency requirements of RF applications have reached the GHz range, and analog and digital methods have made modulation technology more and more complicated. In addition, there are more and more standards in the RF communications industry. For RF signal source designers, the first challenge is to implement multiple RF test signals in a single system. For example, RF signal sources may need to provide a variety of outputs, such as FM, FSK, QAM, WCDMA, and LTE signals. The bandwidth required to support these RF test signals is now getting wider and wider, making it difficult to find devices that support the wide bandwidth, good linearity, and low noise performance required by these standards. Moreover, for different frequency bands, designers may need to add different signal paths. The second challenge for RF signal source designers is to control the noise floor of the system. The more digital signal processing and RF signal processing used, the higher the radiated noise of the system. The extra signal path also increases noise due to crosstalk, making it more difficult to obtain a clean output. The third challenge for RF signal source designers is the continuous improvement of system capabilities and flexibility. The signal source also needs to support external clock input and modulation input in order to meet the end user's test purposes, such as synchronization. The system also needs to be compatible with interfaces such as USB, GPIB, Ethernet, and RS-232. ADI Solutions Value proposition of ADI solution: 1. One-stop supplier, providing the most complete product portfolio from digital to RF devices, such as phase-locked loops (PLLs), mixers, power detectors, ADCs, DACs, amplifiers, and digital signal processors. 2. Rich RF design resources, including easy-to-use simulation tools (ADIsimPLL, ADIsimRF, ADIsimSRD, ADIsimCLK), RF cells in the ADI Chinese Technology Forum, fully populated evaluation boards, etc. 3. The compatibility of ADI products supports design migration between multiple platforms. For example, pin-compatible high-speed ADCs provide a variety of different sampling rates and resolutions. 4. On-chip integration can optimize signal chain performance, reduce board space, and reduce BOM cost and power consumption; for example, the power management unit (PMU) integrates linear regulators, switching regulators, and power monitoring functions. 5. Circuits from the Lab circuits are tested reference circuits that help speed up design while simplifying system integration, helping and solving today ’s analog, mixed-signal, and RF design challenges. Web-based design tools can optimize the performance of custom designs.
