I understand that. Why do you think this isn't already a good IQ stream? The max2830 has the 90 degree hybrid built in (like every IQ demodulator I've ever seen

- mikewarot 2y agoBecause at baseband they go around the max2830. A 90 degree hybrid for 100 khz all the way to 25 mhz isn't going to be small, so I can see why they didn't include it.
- Neywiny 2y agoAh. I missed that. But you wouldn't put a filter, you'd do what's called digital downconversion or DDC. This is doing the IQ demodulation in software. It's not a phase shift, it's a different type of block.
