Summary: | The invention provides an ultra-wideband radio frequency receiving channel and a working method thereof. The ultra-wideband radio frequency receiving channel comprises a low noise amplifier (3), a radio frequency filter bank (4), a sampling holder (5), an intermediate frequency filter bank (6) and a processing unit (9) which are connected in sequence, and a choke inductor (7) and a blocking capacitor (8) which are connected with the sampling holder (5), and the low noise amplifier (3) is connected with the receiving antenna (1) through the amplitude limiter (2). In the ultra-wideband radio frequency receiving channel, a sampling holder is multiplexed, and ultra-wideband radio frequency signals of a KU wave band and all frequency bands below the KU wave band are processed in one radio frequency receiving channel, so that the ultra-wideband radio frequency signals can be directly sampled by AD. Compared with other receiving channel schemes, the ultra wide band and high dynamic are ensured, and the link is conci |
