This is the circuit diagram of 900MHz RF amplifier built based transistor BFG480W manufactured by Philips. The circuit features low noise, good linearity performance and works well for high frequency application.
This is the initial conditions apply for the amplifier design:
- Vsupply » 3.6 V
- VCE » 2 V
- IC » 20 mA
- f = 900 MHz.
- |s21|2 » 15 dB
- VSWRIN < 2
- VSWROUT < 2
- NF </= 2 dB
- IP3i > 9 dBm.
on both emitter-leads to improve the matching and the noise figure.
