10dB 4-Port Coupler 617-3800MH z 200W -161dBc 4.3-10 IP64

Please Register or call for more information

The CK-16LE and CK-17LE 4-port Directional Couplers are 
a tapered strip line design covering from 617 to 3,800 MHz 
for CBRS and Band43 applications. Units couple off a defined 
fraction of signal with minimal reflections or loss.
The extremely wide frequency range allows use with mul-
tiband antennas, leaky cable systems and wireless base sta-
tions. With minimal solder joints and a low loss dielectric, the 
dissipative loss has been minimized and reliability enhanced. 
Mounting brackets are included.

  • Extended bandwidth for CBRS and Band43 applications
  • 6 & 10 dB Coupling Values
  • Minimal RF Insertion Loss
  • Guaranteed Low PIM
  • 200 Watt Average Main Line Power
  • 4.3-10 Connectors
  • RoHS Compliant
