Hi, everyone,
I'm learning the RF's circuit. I want to know how to calculate the value of
RFC(RF choke coil).
 
Re: bias circuit

the RF choke coil , 10 times the impedance at the point

khouly
 

Re: bias circuit

thanks.
For example, at 433MHz, how much of th coil?
Can I use the XL=2*Pi*f*L , 50ohm = 2*3.14*433M*L?
then the L=?
Is it right?
 

Re: bias circuit

yeah , as a first order hand calculation yea, then u need to check with some RF simulator to check the circuit work well or not

khouly
 

Re: bias circuit

thank you very much
 

bias circuit

10 times larger than the input impedence of the bias point
