RC filter loss amplitude
You can try to use the inductance instead the resistance
-->L = 200/(2*%pi*10000)
 L  =
    0.0031831
around 3.2 mH U can use small SMD standard 1000uH in the serial line (3x1000) 
If it's value is too high, you can try to increase the capacitance, but it will decrease the amplitude
