摘要：
This paper presents an over-voltage protection circuit with low capacitance loading and small size. Its operation principles and measured performance will be presented. As a case study, a 5.4-6.0 GHz InGaP/GaAs HBT power amplifier with this compact over-voltage protection circuit, resulting in no degradation in PA performance, is demonstrated.
