Description
Summary:A fully integrated RF single-conversion heterodyne receiver front-end for ISM band (2.44 GHz) wireless applications is presented. The circuit realizes a high image rejection by exploiting a band pass low noise amplifier and an image-reject mixer according to the Hartley architecture. The front-end has been designed on a 50 GHz cut-off frequency bipolar process. The main characteristics of this design are an overall image-rejection greater than 57 dB at 110 MHz of intermediate frequency, a transducer power gain of 32 dB, a bandwidth of 80 MHz, an input linearity range up to -20 dBm, a power consumption of 96 mW, and finally, it does not require external components.
