180 hybrid coupler
building block to realize Butler matrix is the 90° hybrid coupler, which is a 2×2 hybrid network with equal split of the input power, providing a quadrature phase response across the two outputs [10]. In place of 90° hybrid couplers, a different design procedure using the 180° hybrid couplers have been proposed in [11].A new 180° hybrid-coupler structure based on coupled lines is proposed. It consists of two quarter-wave coupled-line sections and one half-wave transmission-line section. The coupled outputs are ...

Description: division of power into two transmission lines with 90 degree separation of phase. Features: 3 dB 90° - up to 40 GHz 3 dB 180° - up to 26.5 GHz High Isolation, Low VSWR KRYTAR's Hybrid Couplers offer wide frequency coverage in. Average Power: 20 watts.A new class of wideband multisection 180/spl deg/ hybrid rings using the vertically installed planar (VIP) coupler is proposed. On the basis of the reconfigured ideal single-section 180/spl deg/ hybrid ring (i.e., the 180/spl deg/ hybrid ring with an ideal phase inverter), the multisection 180/spl deg/ hybrid rings can be realized by properly cascading of single-section 180/spl deg/ hybrid ...HYBRID COUPLER compared to a distributed branch-line 3 dB coupler designed at the same frequency. A lumped hybrid coupler such as this may be used in I-Q modulators and demodulators,in balanced ampli-fiers for VSWR improvement at the input and to increase output power at the output, in single-ended mixer design, and other circuits.
