    Can someone recommend an IC to use as a wide band amplifier in RF signal tracer? I need an amplification stage between the probe and the audio amp. I would need something in the range of 455 kHz to at least 110 Mhz.

    Thanks,
    Bill Shamblin

    Hello,

    You could try some MMIC's.

    Here is an overview for the MMIC's:

    Here is a datasheet for the MAR6.

    Here's a top secret trick for signal tracers. (Shhh...don't tell anyone!) The typical R.F. detector probe uses a germanium diode for the detector...you need about a quarter of a volt for this to conduct, so it's not all that sensitive. If you use a Schottkey (hot carrier) diode for the probe, there is NO forward voltage drop...and it is MUCH more sensitive. This alone could make your additional preamp unnecessary. :)

    Thanks Bertus and KL7AJ. That sounds like a great idea about using the Schottkey. I will try it out.

    Thanks,
