1+1 RF Switch for 15W Backup TX Systems
In this configuration, the optional ASI board is required and has to be mounted in the
redundancy device (i.e. TX B). With the prerequisite fulfilled, the RF Switch board can
be used as a high power (15W OFDM max.) RF switch. In this configuration, the TX B,
in the condition with no TX A connected, must be able to open up the RF loop to avoid
“hot switching”.
