A C To Ku Band Ultra-wideband LNA With RLC-Feedback And T-matching Network
In this paper, a C to Ku band ultra-wideband low noise amplifier (LNA) are presented. By employing an RLC series network between the gate and drain of the transistor, the LNA circuit can operate at a wide frequency band while maintaining a stable impedance due to feedback of the RLC series network. In addition, a T-matching network is introduced as the inter-stage matching to increase power transfer and achieve frequency filtering. Using a standard 0.25um phemt GaAs process, the proposed LNA exhibits 14 dB gain and a noise figure of 2.3 dB to 3.5 dB from 6 to18 GHz, while the input and output return loss are less than 10 dB, respectively.
