Abstract :
A high gain, ultra wideband and low noise SiGe/BiCMOS distributed amplifier for a 4G multiband, multimode mobile terminal is presented. The proposed SiGe/BiCMOS cascaded single stage distributed amplifier (CSSDA) has shown 21 dB power gain with power flatness of ± 0.5 dB and return loss less than -10 dB for both input and output over the frequency range from 300 KHz to 15 GHz. This is the first SiGe/BiCOMS HBT based-CSSDA, which combines the active load loss compensation algorithm to achieve the ultra-high gain over one decade of bandwidth using commercially available SiGe/BiCMOS technology.
