A design of broadband multiple-input and multiple-output(MIMO) millimeter wave transceiver system is developed in this paper. The millimeter wave(mm-wave) transceiver system includes the ultra-wide bandwidth baseband data processing unit (BAP), intermediate frequency module (IF), mm-wave frontend and the power module. The developed system can support 4×4 MIMO configuration. The mm-wave frequency of...
In this paper, a 1×8 active antenna array based on frequency shiftable vector modulator (FSVM) module is demonstrated. The FSVM module can flexibly shift the operating frequency band of the vector modulator (VM) while not deteriorating the signal performance. By employing the FSVM module, a 1×8 active antenna array with a RF path beamforming structure is developed. Since the magnitude and phase of...
In this paper, the design of the RF front-end transceiver of base-station for 2600MHz TD-LTE-A communication which bandwidth is 100MHz is provided. High performance is obtained. For the transmitter, the IMD3 is less than −40dB when the transmitting power is 0.2W. In the signal test of 16-QAM modulation, the TX EVM is less than 1.8% under the condition of 10M symbol per second (sps), and less than...
In this paper, the design of a high performance RF transceiver which supports wireless data-rate up to 1Gb/s is presented. The RF transceiver operates at 3.45GHz, the channel bandwidth is 100MHz. Excellent RF performance is obtained. The IMD3 is less than −40dBc when output power is 25dBm. Both TX and RX EVM are less than 3% when tested with a 20MHz TD-LTE signal. The transceiver has a 60dB dynamic...
