Browave
(1x2 and 2x2) coupler series feature exceptionally
low polarization dependent loss on both signal
and tap ports as well as excellent temperature
and excess loss.
These high performance regular parts are available
in a wide variety of tap ratio, housing and connector
options and can therefore be readily specified
in a wide variety application.
Reliability is guaranteed through extensive Telcordia
GR-1221 testing. |

1.Values
are referenced without connector loss
2.Change in insertion loss from -5
to 75.Valuse
are depended on coupling ratio,for 1/99 coupler Temperature
Dependent Loss (TDL)~0.02/0.20 dB.As tap ratio increase
,TDL decereases for tap path,while increases for signal
path All TDL is specified from -5 to 75
3.Operating temperature range changes
to -5 to 75
in 6L,7H package and all package without connectors
4.The mechanical tolerance should be
 0.2
mm on all package dimensions unless otherwise costom
