Guide me for SWG, diameter and turn of 10uH choke.
I found this detail of coils on a transmitter but cannot understand properly:
Coils:
L1= 0.8mm wire, 5 turn on 3mm air core
L2= 10uH choke or, 0.2mm wire, 10 turns in ferrite core
What is the diameter of ferrrite core of L2? How can I make this 10uH choke without knowing its diameter? I have to make exact 10uH because this choke used in sensitive part of the circuit.
I have a ferrite rod of 5mm diameter. And also have a ferrite ring of 1 cm diameter.
Any idea?
 
It sounds like L1 is the critical inductor and the choke is not. But if you can post the circuit we can tell for sure. From the spec. it sounds like the ring is what you want.
