Abstract :
This paper describes a small RF front-end for a 1.9-GHz direct-conversion receiver that uses power dividers of a newly developed type. The developed power divider is passive and its chip size is half that of a divider of the conventional type. The fabricated 1.9-GHz gain-controlled RF front-end has a small amplitude error of less than 0.4 dB and a small phase error of less than 3 degrees for an input signal with a power level below -10 dBm
