The SQ12502 is a 90 degree 3 db hybrid coupler that covers the frequency range of 2.0-4.0 Ghz. They are excellent for equally dividing an input signal into two signals with 90 degree phase difference between them or combining two signals to a common signal. Theoretical loss of these hybrids is 3 dB. These quadrature hybrids are optimized for good VSWR match, high isolation good amplitude and phase balance. Power handling is 100 watts CW.
