This application note documents the feasibility of a low cost 900 MHz cellular device as a commercial FM driver. The device uses the STMicroelectronics product SD57045 LDMOS RF transistor. LDMOS technology allows the manufacturing of high efficiency and high gain amplifiers for FM transmitters. LDMOS has proven advantages against bipolar devices in terms of higher gain, efficiency, linearity, and biasing simpleness that lower the overall system cost and make them attractive for high volume businesses demanding low cost RF power transistor solutions.
