Abstract

The invention discloses an ultra-wideband millimeter-wave up-conversion frequency transmitting device and method, belonging to the field of mobile communications. An ultra-wideband millimeter-wave up-conversion frequency transmitting device in the invention includes a 90dB numerically controlled attenuator unit, a frequency mixing unit, and various switch filters. unit, 90dB coaxial attenuator, frequency conversion local oscillator unit and MCU control unit; each switching filter unit includes 9GHz~21GHz switch filter unit, 20GHz~31GHz switch filter unit, 30GHz~47GHz switch filter unit, 46GHz~67GHz switch filter unit . Mix the input RF signal with the local oscillator signal generated by the frequency conversion local oscillator unit, and cooperate with the post-stage filter to achieve frequency coverage of 5GHz to 67GHz. It has good external suppression, large power output range, high accuracy and good versatility, and can be applied to millimeter wave communication signal transmitters such as 5G and B5G.

Description

technical field [0001] The invention belongs to the field of mobile communications, and more particularly, relates to an ultra-wideband millimeter-wave signal up-conversion transmitting device and method. Background technique [0002] After the development of 2G, 3G and 4G, mobile communication technology has now entered 5G communication, and the coverage frequency band has also been extended from the radio frequency band to the millimeter wave, especially the band n257 (26.5GHz~29.5GHz) and band n258 (24.25GHz~ 27.5GHz), band n260 (37GHz ~ 40GHz), band n261 (27.5GHz ~ 28.35GHz), etc., highlighting the importance of millimeter wave technology, the existing ultra-wideband millimeter wave up-conversion transmission scheme can not achieve large signal. The power output of the range is not high, and the accuracy is not high, which cannot meet the needs of different occasions. Aiming at the actual needs of 5G millimeter wave signal simulation, the present invention proposes an u...
