A broadband RF(Radio Frequency) reception module is provided to up-convert local frequencies outputted from the first local frequency oscillator by double, thereby setting ultra RF frequencies such as microwave bands as maintaining a phase noise characteristic of a basic frequency as it is. The first local frequency oscillator(410) provides a local frequency signal. A frequency multiplier(501) inputs the frequency signal to up-convert the frequency by double, and outputs a converted signal. The first synthesizer(120) synthesizes a high-band RF signal outputted from a low-band RF signal processor(110) with the local frequency signal to output a difference frequency RF signal. A high-band voice signal processor(230) filters, amplifies, and demodulates an IF(Intermediate Frequency) signal outputted from the second synthesizer(220). A microwave band RF signal processor(310) amplifies a microwave band signal detected from a microwave band antenna unit(301). A microwave band voice signal processor(330) filters, amplifies, and demodulates an IF signal outputted from the third synthesizer(320).
