This device has good phase inversion with respect to input and low insertion loss at 1.0 dB maximum. In addition, the coupler has directivity of 12 dB minimum at 4 to 750 MHz and 8 dB at 750 to 1,000 MHz, return loss of 16 dB minimum, and impedance of 75 ohms. With a coupling flatness above 18.2 dB and small size of 0.30inches× 0.31inches it is an ideal part for many applications.
