This thesis describes the design, layout, assembly and test results of a WLAN IF circuit from a system point of view. The IF circuit uses RF2948 IF transceiver together with RFMD 2.4GHz wireless LAN chip set in order to fit the 802.11b requirements.
Chapter 1 gives an introduction, which briefly describes wireless LAN and its basic circuit structure and design procedure. Chapters 2 and 3 present the circuit design based on RF2948 IF transceiver, and it involves the chip function and characteristics. Chapter 2 discusses the IF circuit design and Chapter 3 is for the DC and control circuit design. Chapter 4 then illustrates the circuit layout based on the designed circuits. The layout consideration includes the input and output signal characteristics, circuit characteristics and test requirements. Chapter 5 is on the circuit testing, which presents the measurement results by the specific procedures and testing signals. Finally, Chapter 6 is the conclusion.
