This article presents the design of a novel quad-band LNA operating in the GSM 0.9GHz/GSM 1.8GHz and ZigBee 0.9GHz/WLAN 2.4GHz communication standards. This pseudo-concurrent architecture uses a two bit mode switch for selecting between the frequency bands. An RF switch is implemented before the Low Noise Amplifier (LNA) module to improve the insertion loss and isolation between the frequency bands...
This article presents an original design methodology for the selection of output matching load network for a dual-band Low Noise Amplifier (LNA) that is targeted for the use in the GSM 1.8 GHz and WLAN 2.4 GHz range. A particle swarm optimization (PSO) based technique is used to get the optimized values of the output load network components. The concurrent dual-band LNA is simulated with these entire...
An original design methodology for the selection of output matching network for a concurrent dual-band Low Noise Amplifier (LNA) that is targeted for the use in the GSM 1.8 GHz and WLAN 2.4 GHz range has been proposed in this paper. A particle swarm optimization (PSO) based technique is used to get the optimized values of the output load network components. An RF switch has been incorporated before...
