[Discuss-gnuradio] XCVR 2450 spurs

[hanwen]

Hi *,

I'd like to measure the out-band spurious generated by XCVR2450. 

There is a spreadsheet which can be used for calculating the location of mixer harmonics.

And what I need is the IF and lo frequency.

I guess XCVR2450 use a zero-IF scheme, but why there is a small DUC frequency about 254Hz?

I'm totally a layman of RF and transceiver design.

Thanks in advance!
