Abstract :
In the recent few years, architectures alternative to the classical super-heterodyne receivers, like zero-IF or low-IF, have been investigated. In this paper, a possible solution to enable a high IIP2 front end and suitable for such receivers is described. The designed circuit, implemented in ADS using the OMMIC foundry GaAs-ED02AH process and operating in the 5.8 GHz ISM band, shows an IIP2 better than 50 dBm verifying the improvement of the described front end in comparison a classical approach. Moreover, a direct conversion receiver, including the mentioned solution, has been studied in order to appreciate the main receiver parameters like BER and sensitivity.
