Hello!
Thanks fr the answer!
But JFET have higher noise wrt BJT if the source impedance is low. My source impedance is 50 ohm. And I dont find an SMD JFET with low noise...
Can you elaborate this? I though that adding a series resistor would add additional noise. I already put a 10 ohm...
Yeh, dont trust spice models. I was excited when I simulated an Infineon BAR63 pin diode. I got like 10V/ns, but when I made the circuit, a schottly diode was faster...
Hello!
This is my very first post, but I was lurking for a lot of time!
I need your advice on a 10Mhz to 20 MHz doubler & amplifier.
I have a 10 MHz OCXO 7dBm with a very low phase noise (-160 dBc @ 1kHz) and I have to feed its signal to a PLL, that requires above 150 V/us slew rate.
I have two...
