i design a rf circuit working at 100 mhz. there is a rfc in the circuit to choke the ac signal and it is about 40µh ,but i cannt find such a big inductance working at 100mhz. who can give me some advice? thanks a lot!!
For frequencies of 100MHz you should look for RF chokes in the range of 0.1-1µH, and I am pretty sure you will find planty to choose from ..
40µH RF choke looks better at 10MHz or less applications ..
