Abstract
Circuit solutions of various types of gain controlled IF amplifiers with digital and analog gain control are described. Advantages and disadvantages of the different solutions are shown. Requirements for low‐power, low‐voltage, low noise, high gain and linearity at high IF‐frequencies from the system point of view are worked out. Solutions will be presented to optain optimum performance by technology and circuit design technique for digital wireless telephone systems used for GSM and PCN systems.
