The study deals with the design and construction of a solid-state FM stereo broadcast transmitter. The whole system is divided into four (4) major parts, namely: the modulator, the stereogenerator, the power amplifier and the power combiner.A prototype of the transmitter is constructed and its performance is evaluated based on the electrical performance evaluation standard set by the National Telecommunications Commission (NTC) and the Kapisanan ng mga Brodkaster sa Pilipinas (KBP). The evaluation is carried out using existing and available instruments and equipment.The result of the performance evaluation revealed that the prototype met the specifications required of an FM broadcast transmitter.The prototype is therefore fitted to be used in actual broadcast operations. With a power output of 30 w, the prototype can be used as a low power broadcast transmitter.Aside from the performance evaluation, a comparative cost analysis is made based on the cost of RFpower produced by the prototype and a local-made vacuum tube transmitter
