400MHz LOW NOISE AMPLIFIER WITH THE BFG540W/X

Abstract: This application note contains an example of a Low Noise Amplifier with the BFG540W/X RF-transistor. The LNA is designed for a frequency f=400MHz, VSUP=3.0V, ISUP~7.5mA. Measured performance at f=400MHz: Noise Figure NF~1.0dB, rf-Gain S21 ~15.5dB, Input_IP3~2dBm

Applications: LNA for a 400MHz CDMA system (Chinese market).
