Abstract :
In this paper a low noise trans-impedance amplifier (TIA) is presented between 4.4 GHz and 5 GHz in a GaAs pHEMT technology using a commercial photodiode. Using a narrow-band design´s technique of photo-receiver basis on microwave approaches to design a low noise amplifier, we increase the bandwidth. The photo-receiver provides an equivalent input noise current density of 5.5 pA/VHz at 4.6 GHz.
