A new LNA has been designed using single supply enhancement mode PHEMT process for WCDMA and other wireless application up to 6GHz. The LNA has direct CMOS logic controllable integrated bypass-mitigated switch and LNA linearity (IP3) control switch. Two different kind of logic controls (0/3V, 3/0V) switch has been design for bypass-mitigated switch. In high linearity mode the LNA draws 8.5mA current and has 15dB gain, 1dB noise figure, - 6dBm IP1dB,, 7.3 dBm IIP3 with I/O return loss >lldB. In Low linearity mode the LNA draws 3.5mA current and has 14dB gain, 1.1dB noise figure,, -6.SdBm IP1dB,, 2dBm IIP3 with I/O return loss >11dB. The LNA bypass-mitigated switch has <3.5dB insertion loss & NF, I/O return loss >11dB and draws negligible current with 3/0V logic, ∼200μA for 0/3V logic. Due to well-behaved match of LNA in High Linearity/Low Linearity/Bypass modes, this LNA has minimum mismatch effect for duplexers and filters in a receiver system.
