A multi-band and ultra-wideband (UWB) 3.1-4.8 GHz receiver front-end consisting of a fully integrated filter and triplexer network, and a flat gain low-noise amplifier (LNA) is presented in this paper. The front-end utilizes a microstrip network and three combined broadside- and edge-coupled bandpass filters to connect the three sub-bands. The LNA design employs dual-section input and output microstrip matching networks for wideband operation with a flat power gain and a low noise figure. The system is fully integrated in a four-metal-layer printed circuit board. The measured power gain is 10 dB and the noise figure of the front-end is 6 dB at each center frequency of the three sub-bands. The minimum isolation between the sub-bands is -27 dB and the isolation between the non-neighboring alternate sub-bands is -52 dB. The out-of-band interferer attenuation is below -30 dB.
