This work presents a $75 phase modulated 2.07MHz radiofrequency power amplifier (RFPA) measuring 8.5x4.5cm for Selective Encoding through Nutation and Fingerprinting (SENF). By eliminating the need for a gradient system and imaging in a low B0, SENF shows great potential to reduce the cost, size, and accessibility of magnetic resonance imaging (MRI) equipment. Here we present the development of a transmit stage of a SENF coil unit. Special consideration has been given to simplifications that can be made in RFPA design in this specific application.
