A High Performance Channel Simulator RF Transceiver for 5G Communications

Abstract

The invention discloses a high-performance channel simulator radio frequency transceiver applied to 5G communication, which includes a transmission link and a reception link; in the transmission link, the intermediate frequency signal passes through the first intermediate frequency filtering module, the up-mixing module, The first automatic gain amplification control module, single-pole double-throw switch and radio frequency filter module are finally transmitted; in the receiving link, the radio frequency signal passes through the radio frequency filter module, single-pole double-throw switch, low noise amplifier, second automatic gain control amplification module, The down-mixing module, the second intermediate frequency filtering module and the third automatic gain amplification control module finally receive back; in addition, a local oscillator module providing local oscillator signals for the up-mixing module and the down-mixing module is also included. The invention can effectively reduce the complexity of the channel simulator, reduce the power demand for a single channel in 5G research, reduce power consumption, and has the characteristics of large processing bandwidth, small area, and good performance.

Problems solved by technology

There are two main reasons why traditional measurement methods are no longer suitable for the measurement of 5G massive MIMO digital multi-beam arrays: 1) Digital multi-beam antenna arrays are different from traditional antenna arrays. Traditional indicators that characterize antenna performance are: gain, bandwidth, efficiency, etc. are no longer suitable for an accurate description of the behavior of digital multibeam arrays

2) Traditional antenna measurement methods and measurement platforms use the antenna or array as a single component to measure separately, but for digital multi-beam arrays, antennas and transceivers (Tx / Rx) and even digital-to-analog / analog-to-digital conversion ( ADC / DAC) circuits will be integrated and cannot be separated, which makes the original index parameters that describe the characteristics of the antenna and RF transceiver components alone cannot be applied
