In this paper, RF transceiver for wireless backhaul system was designed and implemented. The requirement of RF transceiver was extracted with system link budget. And, the IF/RF modules composing the transceiver were also designed and fabricated. The implemented RF transceiver was verified with system loop-back test.
Massive multiple-input multiple-output (MIMO) systems are expected to significantly enhance the energy efficiency (EE) and spectrum efficiency (SE). However, RF transceivers introduce huge cost of high complexity of the hardware with the antennas increasing. In this paper, considering the low-complexity hybrid structure, we propose a hybrid precoding scheme to approach the performance of the traditional...
In order to expand the application domain of field programmable gate arrays (FPGA), a highly-integrated wireless configuration scheme is presented by transfering the configuration data with RF method. To fulfill the configuration system, three key hardware portions are necessary, including the configuration controller in FPGA, the RF data channel and the configuration host. In this paper, the central...
This paper presents a novel 90 GHz band RF transceiver using polarization-division duplex (PDD) technology. A PDD architecture is used for full-duplex communication in the single band. The RF transceiver can deliver 6 Gbps through six channels with a bandwidth of 3 GHz. The channel bandwidth is 500 MHz. A IF combining structure is used for multi-channel. To implement the system, a fourth-harmonically...

In this paper, we describe a design of the hardware interface and communication process of a wireless data acquisition system using a monolithic CC1100 chip working with a PIC16Fxxx MCU. The design has been applied to collect data during the transportation of petroleum products in the petrochemical industry. The fault tolerance problem in the one-to-many data communication is solved. This paper also...
An RF transceiver for operation near 24 GHz with an onchip antenna, fractional-N synthesizer and other RF and analog baseband circuits is demonstrated in 130-nm CMOS. A 5-m wireless link was demonstrated using a transceiver pair. A technique for wireless calibration of an on-chip frequency reference is also demonstrated.
In this paper, a process tunable, continuously adaptive wireless front end architecture and related adaptation algorithms are presented that allow an RF transceiver to function at minimum power irrespective of channel conditions and process variability induced performance loss in the RF front end and baseband interface. Current wireless transceiver front ends are designed for worst case channel conditions...
