3 usable transistors for radio & and (V) HF circuits, all of them surely work between (say) 2 MC and 30 MC. Or even higher and surely on lower frequenc. This is a further progression in the application of the J310 JFET in high performance preamplifiers. This one is designed to amplify the 20KHz to 30 MHz range, uses the premium J310 FET and 2N5109 CATV bipolar transistors, giving a good combination of low thermal noise, gain and IMD resistance.
