摘要：

A new radio receiver system for personal communications is described. This technology incorporates direct conversion into an integrated circuit in such a way that the need for discrete IF filters is avoided. It also employs a second IF functional circuit that contains a carrier leak detector and an adjustment-free system. The carrier leak detector suppresses the level of unwanted carrier leak and the adjustment-free system automatically compensates for any variation in circuit response that corrupts the performance of the receiver. The resulting design is particularly suitable for use in wireless devices such as pagers and cordless telephones.
