NOTES
1
Operating temperature ranges as follows: A Version: –40°C to +85°C.
2
See terminology.
3
Measured in continuous transmission and Burst Mode with the I and Q channels ramping up and down at the beginning and end of a burst.
4
Headroom must be allowed for the transmit DACs such that offsets in I & Q transmit channels can be calibrated out. Therefore, the full range of the I and Q DACs
are not available to the user. The user should ensure that binary codes greater than or less than the maximum or minimum are not loaded into the I or Q DACs.
5
Measured while the digital inputs to the transmit interface are static and equal to 0 V or V
