Expanded Log Detector Input Transformer

Post by Sam » Wed Dec 28, 2011 2:16 pm

The input transformer of the VGA in the Expanded Log Detector is specified as a Coilcraft type, with a Minicircuits alternate. The alternate is incorrect and should be TC16-161TG2. The one previously specified is TC16-1T, which has a lower spec of 20 MHz. If you used the TC16-1T, it should work fine but the insertion loss is a little higher, so conceivably the noise performance is a little worse.



I personally prefer Coilcraft but the Minicircuits transformers are fine.
