Millimeter-wave monolithic integrated low noise amplifier circuit
Have a good performance,MAC Mascara, input and output standing wave ratio is less than 2, the gain is greater than 20dB, noise figure of less than 4. The chip has been successfully applied in the 24GHz automotive collision avoidance radar receiver front end. References [1] RobertsonID. RFICANDMMICdesignandtechnology.
