900 and 2400 MHz Amplifiers Using the AT-3 Series Low Noise Silicon Bipolar Transistors
This application note discusses the design techniques and performance of the Hewlett-Packard AT-3 series of silicon bipolar transistors as used in typical low noise amplifiers for use in the various commercial markets. Although specific designs are presented for 900 and 2400 MHz, the techniques are applicable to other applications in the VHF through S Band frequency range. 900 and 2400 MHz Amplifiers Using the AT-3 Series Low Noise Silicon Bipolar Transistors This would include the 450 MHz (Mobile Radio),
