Hello, does the ADRF6821 chip work down to around 190 MHz? Do you have data at lower frequencies? Thanks 

  • Hi,

    The datasheet minimum is 450 Mhz.  I don't have have data at 190 Mhz RF input, but you would need to consider potential roll-off of the input balun along with LO performance, depending on the IF desired.  Can you share any other details, i.e.:   IF Freq, Bandwidth, Desired Linearity, etc ?
