[NLRS] Mixer Conversion Loss

In a brief nutshell, what exactly is "conversion loss" in, for example,
a Doubly Balanced Mixer module from Minicircuits such as a TUF-1MH+ ??
Spec for this mixer says conversion loss (typical) of ~5.5 dB at ~144
MHz. This mixer uses +13 dBm of LO which I have available. So, if I
inject the IF (28 MHz) at 0 dBm at the mixer's IF pin, what would I
expect out at 144 MHz at the RF pin? Perhaps -5.5 dBM??? Or, does the
LO power come into play in figuring the RF output? I'm re-designing
(updating) a very old design 28-144 transverter that I built over 10
years ago (basically, I'll be using the original LO module and building
new mixers and PA).
