R1 and R2 are used as a voltage divider for biasing the JFET.Ī typical value for 12V operation could be: R1 = 100k, R2 = 10k, RC = 10k, and C1, C2 can be 1uF ceramic capacitors.

The RC is the collector Resistor and changing this value will change the frequency response of the circuit as well as it will control the DC gain by controlling the collector current. The C1 is the coupling capacitor and the C2 is the DC blocking capacitor where the output will be harvested. The below image is showing the standard application of the N-Channel JFET 2N3819 as an amplifier. 2N3819 works up to 100mA of continuous Drain current (I D). Choose a JFET that could tolerate more than the Drain current that is actually required for the application. 2N3819 supports 25V Drain-Source breakdown voltage and 25V Gate-Source Breakdown voltage.

Choose a JFET that has the Drain-Source and Gate-Source breakdown voltage more than what is actually required. MPF102 Datasheet PDF - JFET VHF Amplifier.

Calculate the maximum Drain-Source voltage, and the Gate-Source voltage will be for the targeted application.

I had 15 MPF102s, which I had previously matched for resistance (Rds) at two points: 1 kohm and 20 kohms. Well, after posting this circuit yesterday in the afternoon, I continued at night with the experimentation on the Phase 45. If the application requires high side switching, then use P-Channel. Greatly Improved JFET Matcher is here « Reply 11 on: February 04, 2005, 06:03:35 AM ». Abstract: MPF-102 pin out mpf102 Application Note MPF102/D Text: MPF102 Preferred Devices JFET VHF Amplifier N Channel Depletion Features, DIAGRAM MPF 102. 2N3819 is an N - Channel JFET thus it is suitable to use on the low side of the power path. It is mainly designed to use in VHF and UHF circuits but it is not limited to only these applications and can also be used in other type of applications. The transistor is available in TO-92 and SOT-23 packages.
