Description: The FM302E-I-type FM transmitter exciter is manufactured by NEC Corporation, Japan, and features a 1210 motherboard. It utilizes direct frequency modulation of the carrier signal, employing phase-locked frequency stabilization and frequency synthesis techniques. The front power amplifier is based on the BLF-177 FET.
The FM302E-I-type FM transmitter exciter is designed to provide high-quality FM transmission with precise frequency control. The use of phase-locked loops (PLLs) ensures that the output frequency remains stable and accurate, which is critical for broadcasting applications. This stability is achieved through advanced frequency synthesis methods that allow for rapid adjustments in the carrier frequency while maintaining signal integrity.
The core of the transmitter's functionality lies in its 1210 motherboard, which integrates various components necessary for signal processing and modulation. The direct frequency modulation technique allows for efficient transmission of audio signals by varying the frequency of the carrier wave in accordance with the input audio signal. This method enhances the fidelity of the transmitted audio, making it suitable for high-fidelity broadcasting.
The front power amplifier, utilizing the BLF-177 FET, plays a crucial role in boosting the signal power before transmission. The BLF-177 FET is known for its high efficiency and linearity, which contributes to improved performance and reduced distortion in the transmitted signal. This amplifier is designed to handle significant power levels, ensuring that the FM transmitter can operate effectively over a wide range of distances.
