【经验】如何测试并计算FM/AM音频广播接收芯片Si4730的音频输出幅度?
Si4730是SILICON LABS推出的一款FM/AM音频广播接收芯片,因其优异的性能和极具竞争力的价格,在消费类收音机市场上得到了广泛的应用。最近有客户在应用的过程中反馈AM的音量小于7dB。本文以该问题来分享一下音频输出的强度应该怎样测试和计算。
测试AM音频输出强度(dBμV),我们的测试调方法是:
信号发生器设置1040KHz,30%调制度,1Khz音频载波,信号强度74dBuV;待测芯片在EVB的控制下进入AM模式进行搜台;示波器测量芯片音频输出引脚的信号(峰峰值或者有效值)。
示波器测试峰峰值:
峰峰值230mV,则:230mV/2*√2=230mV/2.828≈81mVrms=20log81000≈98dBuV
测试单位之间的换算公式:
峰峰值(mV)/2*√2=有效值(mV)
信号强度(dBuV)=20log(1000*有效值)
本次测量的结果与正常芯片同样测试条件下测得的结果一致。所以说明该芯片AM的输处是正常水平。

【经验】两颗收音芯片Si4730的双Tuner单天线设计,如何避免互相干扰
随着收音机功能的增多,为了满足客户的不同需求,很多收音机设计会用到双Tuner单天线的设计,比如用到两颗Silicon Labs的收音芯片Si4730。一颗芯片接收当前播放的信号,另一颗芯片做背景扫描等。单天线双Tuner,天线到Tuner信号输入端的信号衰减严重,两颗Tuner互相干扰,灵敏度都受到了影响。所以建议在需要这样的应用时在天线端做好隔离,本文提供电路参考。

游艇WB天气预警接收机需要接收美国NOAA WB天气预警频道,有哪些产品推荐?
美国NOAA WB接收方案有两种:1、FM/AM/WB是分时工作的,推荐Si4736(RDS Si4737)在不同工作模式下分别接收FM/AM/WB;2、WB和FM/AM接收需要同时工作,WB由单独的芯片Si4707或者Si4736(RDS Si4737)来接收,而FM/AM由Si4730(RDS Si4731)接收。此时Si4730/31芯片在前台做FM/AM接收工作,而WB接收芯片Si4707或者Si4736(RDS Si4737)则处于后台接收状态,当接收到WB 1050Hz预警信号时自动切换到前台工作,或者在不接收FM/AM信号时手动切换到WB模式。
