We demonstrate a heterodyne wireless system using only ErAs:In(Al)GaAs photoconductors driven by two independent telecom laser signals. The maximum Intermediate Frequency (IF) was 2.3 GHz, only limited by the bandwidth of the post-detection electronics. The maximum signal-to-carrier ratio achieved was 42.6 dB.
