The C9303 from Werlatone is a Dual Directional Coupler that operates from 2000 to 2400 MHz. It has a coupling value of 40 dB with directivity of 25 dB and an insertion loss of 0.2 dB. The coupler can handle a CW input power of 500 W and has a VSWR of less than 1.3:1. It uses two 3-Port Uni-Directional Couplers, which are internally connected, in tandem for providing a measurement of both forward and reverse power. It is available in a module measuring 3 × 3 × 1.09 inches with N-type female connectors and is RoHS compliant. The coupler is ideal for monitoring forward / reverse power and for reflectometer measurements.
