For the purpose of conserving power I'd like to disable the LTC5553 via the built-in EN-Pin. Unfortunately, I cannot disable the LO-Signal feeding the LTC5553. Is it ok to have RF-Power at the LO or even the IF-Input while the part is in disable mode?
Thanks in advance and best regards
It is OK to have signals applied while the part is disabled. The only constraint is that the Absolute Maximum Ratings (datasheet page 2) are not exceeded.
