摘要: A voltage-voltage feedback, frequency-tunable LNA and I&Q variable-gain mixers are realized in a 0.25/spl mu/m SiGe BiCMOS technology. The front-end, suitable for multi-standard applications, shows the following performance 4.9 to 5.825GHz band: 31.5dB gain, 2.5dB NF, -9.5dBm IIP3, 23dBm IIP2 while drawing 16mA from 2.5V.
