problem with mosfet amplifier circuit

[rakirajueee08]

I have a problem with my amplifier circuit.My input to gate of mosfet is 2Mhz from microcontroller and bias voltage is 30v.when I measure voltage at the terminal of the dc blockin capacitor as i have given in the following picture it shows voltage low close to zero and the frequency about 300 khz.what is the problem ?Because according to the principle it should give amplified voltage and frequency the same at the input is 2 Mhz.please help me someone.

From the data sheet ( https://www.futurlec.com/Transistors/IRF510.shtml ) you need at least a +4V input to the gate to switch the fet s drain current on, are you getting this at the gate? - which should have a DC return to the drain (100K ?)

Hi frank, you probably meant

... return to the source

I think ..

yes i geeting that required current .now i am giving the 2mhz signal from a signal generator .it is not working ? what can i do and what could be the problem?
