Couplers
500 Watt High Performance
Directional Couplers - N TNC Types
500 MHz to 18.0 GHz Frequency Range
Low VSWR - High Directivity
500 Watt High Power Capability
Individually Calibrated
.175 (4.4) DIA
THRU TYP
Midwest Microwave's series of High Power
Directional Couplers are useable for system or
testing where flat frequency response over
extended bandwidths is required. They pos-
sess high directivity and will withstand high
input power under extreme environmental con-
ditions. Standard units have stainless steel
Note: Case Style 7 has two mounting holes.
Type N female connectors but are also avail-
able with TNC connectors.
