In data communication system, the outdoor of Wireless Local Area Network (WLAN) technology can be implemented in bridge connection. It allows LANs in separated buildings to be connected over the distance ranging in several hundred meters. In RF system design level, the performance of the WLAN bridge also relies on the RF receiver system where it must be well designed to minimize distortions in the system. This paper presents a RF receiver system design for WLAN bridge at 5725 - 5825 MHz based on IEEE 802.11a standard. At 54 Mbps data rate, the receiver can receive minimum input power of -69.1 dBm with 19.84 dB SNR and 47.3 dB dynamic range which is comply with the standard. Beside that, the prototype of the RF receiver has been measured to verify with the simulation results in terms of gain compression and spurious responses.
