“…Many researchers investigated the configurable low noise amplifier, power amplifier, phase‐locked loop, and filter in RF front‐end transceiver, to make the communication system reconfigurable 26,27 . Gain variability and bandwidth tuning have been demonstrated in the majority of proposed reconfigurable mixers by the current variation, load tuning, and so forth 28–34 . Other output characteristics, such as noise figure and linearity reconfiguration, must be considered into the mixer architecture in IoT systems as well as energy efficient routing protocol for mobile communication and wireless sensor network field 35,36 .…”

Summary In this paper, a design of reconfigurable frequency mixer is adapted with gallium nitride high‐electron‐mobility transistor (GaN HEMT) architecture under variable gain, different intermediate frequency (IF) bandwidth, and active/passive configuration for multidisciplinary applications supported by wireless local area network (WLAN) framework. The low band (LB) and high band (HB) are reconfigured by shunting the power between the switching and transconductance at the IF stage of the transistor. The transistor switching mode (active and passive) and logic levels are fixed at the input stage, and the input radio frequency (RF) signal is steering between the gate and drain terminals of transistors. The transistor gain is controlled by adjusting transconductance at the input RF stage and the current‐steering in transimpedance stage at the output. The simulation results show that the proposed circuit provides variable gain of 23/25 and 30/32 dB and noise figure of 14.5/12.5 at the LB and HB reconfigurable scenarios. Hence, it is suitable for transceiver optimistic functions with converge large bandwidth through shunting stages of reconfigurable frequency mixer and transconductance.
