IEEE 802.11a The IEEE 802.11a is a standard for Wireless Local Area Network (WLAN) communication. The 802.11a standard uses the same core protocol as the original standard and was the first of the 802.11 family to operate in the 5 GHz band. It uses a 52-subcarrier orthogonal frequency-division multiplexing (OFDM) with a maximum raw data rate of 54 Mbps, which typically yields a throughput in the mid-20 Mbps. Today, many countries around the world are allowing operation in the 5.47 to 5.725 GHz Band. The required specifications of the RF front-end receiver are listed below SpecificationGSM 1900 4900 - 5900Frequency Band (MHz) 20 MHzChannel Bandwidth -75 dBmSensitivity > 80 dBDynamic range 54 MbpsMaximum bit rate We need to choose the components of the receiver to verify the above required specifications. The receiver has the following block diagram: Determine the specifications required for the BPF, without design. The specifications of the Band-Pass Filter (BPF) to be determined are: Center frequency F_0, Bandwidth, IL and Ripple (dB). Choose the Low-Noise Amplifier (LNA) to have ultra-low noise figure, high P_1dB, IP_3 that is at least 12 dB higher than P_1dB. Choose the RF Amplifier (RFA) to have high gain. Choose the mixer to meet the following requirements: Excellent input IP3 performance for down conversion for mobile applications. High input 1 dB compression point to enable the RF port to accept a wide range of input signal levels. Low conversion loss. High LO-RF isolation. Up to 300 MHz IF frequency response to satisfy GSM receive frequency plans. Choose the Local Oscillator (LO) to be PLL-based frequency synthesizer with integrated VCO, to have ultra-low phase noise. Determine the frequency range of the LO to have an IF of 100 MHz and high image rejection. Finally, determine the noise figure, the Linear Dynamic Range (LDR), and the Spurious-Free Dynamic Range (SFDR) of the receiver. Compare your designed receiver to some existing System-on-Chip (SoC) ICs.
