Polyphase filters are widely used in radio frequency (RF) receivers either to generate accurate quadrature signals or to reject the image. Analytical modeling of passive polyphase filter suitable for RF front-end applications is exposed. This analytical study has been used to calibrate the optimal values of passive components in order to obtain the maximum image rejection ratio (IRR). Component matching...
Polyphase filters are an efficient solution for high image rejection and great accuracy quadrature generation in radio frequency (RF) receivers. Analytical modeling of passive polyphase filter suitable for RF front-end applications operating in 2.4 GHz frequency band is dealt with. This analytical analysis has been used to calibrate the optimal values of passive components in order to obtain the maximum...
