Original question:

LMX2492 Ramp delay from trigger?

LMX2492: Can I add a delay to the Flags on TRIG1 and TRIG2 ?

Part Number: LMX2492

Hi,

I'd like to use the LMX2492 in a chirp radar. To enhance Tx/Rx isolation ; I'll need to switch off my Tx PA and the diplexer between PA/LNA/Antenna.

The PA needs some time (~500ns) to get to its nominal output power and the switch needs also some time (~10ns).

Can I, using the LMX2492, switch my SPDTs through TRIG1 ~10ns before the start of my ramp ? And can TRIG2 be on a rising edge ~500ns before the start of my ramp ?

Best Regards.
