Bias T
Posted: Tue Apr 24, 2018 5:50 am
I stupidly pumped 12V into the antenna socket from another receiver. I forgot that it had a 12v bias tee. The RSP1A still works but I have blown up the bias T drive. Looking at the board I know I have destroyed the device marked CA1 and possibly the device marked CJZ. Can anyone identify these? The one marked CA1 I think is a dual FET probably 2n7002 but there are many variants of this device.I'm not expecting that the full schematic will be released but info on this part of the circuit would be helpful. Thanks.
