Hi speed relay solid state

  1. Has anyone seen a solid state relay that will switch a signal of 2-3
    MHz at speeds of up to 1KHz?

    If not, what would be the highest practical limit for this type of

    The intent is to produce a crude modulated signal.

    Continuous duty rating would need to be about 30 watts.

    Thank you for any pointers.

  2. You're basically looking at a mixer.
    You could try to build one yourself
    with a set of power shottky diodes.
    Make sure to consider what happens
    with the reflected power.

    The limitation is not the speed, it is the 45dBm power level. You will
    have to go custom or shell out big bucks for a niche market switch. From
    your description, it is understood that you have a single channel that
    is turned on and off- sounds pretty simple.

    Sounds pretty easy. Look at CEL.COM for the NEC ssr's. At your speeds,
    expect some asymmetry of on/off switch times and a bit of off-state
    feedthrough from capacitance, but "crude modulated" won't be hard.
