Re: DSP ULR antenna uH values?



About the 1.5 thing, they are talking about impedance matching...

From the Si 4734/35 document:

An air loop antenna is supported by using a transformer to increase the effective inductance from the air loop. Using a 1:5 turn ratio inductor, the inductance is increased by 25 times and easily supports all typical AM air loop antennas which generally vary between 10 and 20 µH.
