I have an antenna signal amplifier circuit using MFE201 which is hard to
get.
6v goes to gate 2 via 100K/220K voltage divider to ground from a 9v
battery. Gate 1 is signal via 0.01uF and is also tied to grounded
SOURCE via 1M resistor. Drain is output through 0.01uF cap with 10K
pot. adjustment to ground via either 0.01uf or the tap on pot. and 100
ohms and a 10uF cap. to ground.
Thinking I might(?) use 2 MPF102's by connecting sources together and
drains together.
Am I way off?
MFE201 --------------MPF102
DSS=20v--------------Vdg=25v
GSS=30v--------------Vgs=-25v ??
Id=50mA--------------Ig(fwd)=10mA ??
Power-360mW--------Pwr=350mW
Schematically it looks OK but am unsure of reading FET specs.
