DC5158
Microwave Devices, model
372.47 bi-directional coupler is designed for use in the 0.75 - 1
GHz range and has two incident taps and one reflected, all with
"N" connectors. The reflected port is down 55.0 dB @ 875 MHz, incident
#1 is down 53.0 dB @ 875 MHZ and incident #2 is down 65.0 dB
@ 875 MHz. Because we do not have full nomenclature, we cannot
say for certain what the power limit is, except it appears to
be quite high. Naturally it can be used outside the 0.75 - 1 GHz
range taking into consideration any adjustments to the sampling
ports attenuation.
