NPN Silicon
Low Noise Transistors
Motorola’s MRF949 is a high performance NPN transistor designed for use in
high gain, low noise small–signal amplifiers. The MRF949 is well suited for low
voltage wireless applications. This device features a 9 GHz DC current
gain–bandwidth product with excellent linearity.
