Mikroe RadioStation Click Board™
MikroElektronika无线电台Click Board™设计用于通过FM无线电频段播放音乐。该click板采用Si4713-B30 FM广播立体声发射器，工作频率范围为76MHz至108MHz。通过为该click板配备小型FM天线，即可扩展广播范围。RadioStation Click板将音频信号指向Si4713-B30的低噪声模拟输入端子，在此衰减并转换为数字格式。板载数字信号处理器 (DSP) 可提供音频动态范围控制和信号调制以实现最佳聆听体验。该无线电台click板设有高质量的集成FM无线电发射器。该无线电台Click板采用先进的音频处理技术，一方面可避免过度调制，另一方面可在广播过程中实现出色的音频质量。数字中频 (IF) 信号被滤出并发送到输出级混频器，从而转换为射频信号。该款无线电台Click板适用于MP3播放器、便携式媒体播放器、个人电脑、手机和无线扬声器等应用。
The RadioStation Click Board uses advanced audio processing techniques to avoid over-modulation and to achieve perfect levels of audio for broadcasting. The digital Intermediate Frequency (IF) signal is filtered out and sent to output stage mixer where it is converted to a radio frequency signal. The RadioStation click board is ideal for application in MP3 players, portable media players, personal computers, cell phones, and wireless speakers.
