V-Line Dual Band Directional Coupler
Home >Directional Coupler > V-Line Couplers

V-Line directional couplers cover all wireless bands from cellular through UMTS (0.800 - 2.200 GHz) making them ideally suited for BTS and In-Building Wireless applications. Typically available from STOCK!

Twenty-seven Directional Coupler models are available in single and dual coupling configurations, in both N-Type and SMA connector styles, with your choice of 6, 10, 20, 30 or 40 dB coupling. Unique air-line design and matching techniques provide high power capability (up to 500 watts), the lowest possible insertion loss (less than 0.1 dB), high directivity (25 dB) and exceptional VSWR (1.15:1 typ).

3dB Hybrid Ring 3 dB Hybrid Couplers
A 3 dB, 90° hybrid coupler is a four-port device that is used either to equally split an input signal with a resultant 90° phase shift between output signals or to combine two signals while maintaining high isolation between them.
3dB Hybrid Ring 3 dB Hybrid Ring (0°/180°)
A hybrid ring is a four-port device that is used either to equally split an input signal or to sum two combined signals. An additional benefit of the hybrid ring is to alternately provide equally-split but 180 degree phaseshifted output signals.
