Directional Couplers

AMCrf provides a variety of single and dual directional couplers covering a frequency range of 800 MHz – 2600 MHz. High directivity of 25 dB/min, low insertion loss of 0.3dB typ and a VSWR of 1.2:1 makes them extremely valuable for inline monitoring and power measurements at CDMA, PCS, WIFI and WCDMA frequencies. Standard coupling values of 10,20,30,40 and 50 dB are available. SMA and N type connectors are used as in/out and coupling connectors. Custom designs are available for smaller standard coupling values.
