In this letter, we propose a simple and accurate equation for the estimation of the l-dB power gain compression point (P1dB) in the active bandpass filter. The derivation of the equation is performed on the assumption of a nonlinear parallel conduction model of the active resonator used in the filter. The P1dB's of two- and three-stage bandpass filters calculated front the proposed equation show very good agreement with the data obtained in a commercially available microwave circuits simulator. A P1dB enhancement technique based on this equation is also described.
