phase shift

Post by david753 » Sat Mar 12, 2005 12:42 am

I am looking for a phase shift component with 26mhz low pass filter that can shift its phase digitally.
It will be implemented in my receiver project.
Does anyone can give me idea?

We need more specifics, like the range of frequencies that have to be phase shifted, and the number of degrees needed, and the tolerance in degrees and dB.

I want to make a phase shifter that can shift the phase 0-90 degree of PLL that role as a local oscillator.
I prefer the existen IC in the market.

A Johnson counter, divide by 4, has outputs that are 90 degrees. You could switch between them.
