title = "Ring hybrid balun with good amplitude and phase balance",
abstract = "We present a ring hybrid balun with additional two λ/4 short stubs, which offers excellent amplitude and phase balance characteristic. In the proposed scheme, the phase and amplitude imbalance essentially occurred in the conventional ring hybrid is alleviated by a λ/4 shorted stub and the second stub with a series resistor respectively. The measured data shows that phase imbalance is less than 2.5° and magnitude imbalance is less than 0.2 dB over a 1.75-2.25 GHz.",
