How do we know what it has with no schematic available? It could be $1-2
worth of parts.
I recommend that nobody buy anything from DXE that does not support an at
home repair.

By the way Buck, there is more to this than some people will tell you.
The DXE switch uses a unique RF limiter that kicks in hard at about 23
dBm. Below that level there is no intermod at all!! It will not
deteriorate the receiver, like normal cheap back-to-back diode systems.
If you need a receiver limiter and do not want to hurt receiver dynamic
range on modern receivers, it takes far more circuitry than cheap
back-to-back diodes.
