    Hello

    Any suggestions of npn low noise small signal transistors who goes up to arround 500 mhz ?

    Thank

    Bye

    Hello,

    Do you have more specs ?
    Voltage, current , power ?
    Perhaps take a look at the BFR96.(see datasheet).

    Greetings,
    Bertus

    Hello

    The circuit will work at 5v voltage at arround 30 ma.

    Thank

    Hello

    I know BFR96 and also BFR92, they goes up to 5ghz.

    A bit high for my use and I can not find any of those here arround.

    Here is the circuit, it is a low jitter clock.

    They suggest transistors with about six time the max crystal frequency.

    Thank

    Bye
