Abstract :
We have newly developed an analog front-end with low phase noise, low intermodulation and high linearity characteristics which is applicable to an OFDM system. The double conversion architecture using the GaAs mixer ICs, a low phase noise local oscillator construction and a delayed gain control system are discussed
