N-Channel MOSFET amplifier

Product conditions: N-     

N-Channel MOSFET amplifier

This MOSFET is little known but it has very good performances: low noise 1dBNF at 200 MHz with 25dBG 10 mA, it is a very good HF stage up to 30dBG and it is rated for medium level signals, for HF, VHF and UHF general purpose amplifier, mixer and oscillator

- Forward trasconduttance; 16 mS
- Gate input capacitance: 2.7 pF
- Reverse transfer capacitance: 0.035 pF
- Output capacitance: 1 pF

Simple application diagram, this MOSFET is suggested for all IF and HF applications, for VHF it is better to use a tuned circuit
