EVAL-CN0511-RPIZ

EVAL-CN0511-RPIZ is a DC to 5.5GHz signal generator. It only requires the Raspberry Pi (RPi) to operate. The RF digital-to-analogue converter (DAC), controlled using a 100MHz Serial Peripheral Interface (SPI) from the RPi, allows for single tone, phase coherent, and fast frequency hopping across the spectrum. All the clocking requirements are generated using an on-board crystal, so no external clock source is needed. All the necessary power rails are also converted from the RPi into various supply voltage requirements of the RF signal generator. The system is designed to simplify the input requirements, optimize signal paths, and reduce external cables and components. This circuit can act as a standalone laboratory equipment or can be incorporated as a module into automatic test equipment. Its small size makes it particularly attractive when multiple channels are required. This Raspberry Pi compatible solution makes high speed signal generation more accessible and economical.
