[Premium-Rx] MULTICOUPLER IP2

[Tracey Gardner]

Hi Warren 

Take a look at this ARRL article

http://www.arrl.org/tis/info/pdf/020708qex046.pdf

To quote " In modern receivers, IPs may by quite high. 
It is not unusual to see receivers with third-order intercept
points (IP3s) of +30 dBm (1 W) and second-order intercept 
points (IP2s) of +80 dBm (100 kW). 
IPs form an excellent basis for comparison of receiver
distortion performance"

Looking at that +42dbm in a multicoupler ain't so hot
