"L Impedance Match" to 50 Ohm Coax
|
Merry Christmas to ALL from Los Angeles, California !!!!
1). Need a Formula for designing an "L Impedance Matching Circuit" for matching 50 Ohms to an Antenna with a known Antenna Input Impedance ? ?( Z ). ?Any Web Sites for referral or Formulas ? ? So far have not found any.
2). Question: ?In winding a Toroid there are many ways to get a Turns Ratio of 3:1, such as - 6 Turns to 2 Turns, 9 Turns to 3 Turns, etc. ? Is there a "GENERAL RULE" for determining the number of Turns that is best ?? ? [ I believe EACH winding on the Toroid needs to operate below it's Self Resonant Freq inorder to act as an Inductor. ? ?Maybe for a "Broad Band" Toroid, a Higher Number of Turns ( increases R ) is better because it lowers the Q = Xl / R of the Inductor ??
Any Comments and Help would be APPRECIATED !!!! ? ? ?THANK YOU
