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