ANA#22A

Overshoot and Undershoot During Inter-Chirp Idle Time

Revision(s) Affected:

AWR2243 ES1.0, ES1.1

Description:

At the end of the chirp , when the synthesizer starts to go back to the start frequency of the next chirp, there is some overshoot and undershoot. The undershoot/overshoot is proportional to the chirp bandwidth. Negative slope chirps have a worse undershoot than positive slope chirps.

Workaround(s):

To ensure the TX power amplifier is OFF during chirp idle time and not causing "on-air" emissions during the undershoot/overshoot period, keep the inter-chirp power savings ON.
