PROBLEM TO BE SOLVED: To provide a Cartesian feedback transmitter in which the negative feedback loop bandwidth, as well as the loop gain and the loop phase, can be set at a value which is optimal for the modulation system, transmission rate, transmission power, and the like. SOLUTION: In addition to a gain regulator 15 and a phase regulator 16, variable bandwidth filters 181 and 182 for regulating the negative feedback loop bandwidth are provided on a negative feedback loop. |
