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.
Low Noise Figure, NF min = 1.4 dB (Typ) @ 1 GHz @ 5 mA
High Current Gain–Bandwidth Product, f t = 9 GHz @ 15 mA
Maximum Stable Gain = 18 dB @ 1 GHz @ 5 mA
Output Third Order Intercept, OIP 3 = +29 dBm @ 1 GHz @ 10 mA

MRF949T1 = JL
(1) To calculate the junction temperature use T J = (P D x R JC ) + T C . The case temperature is measured on collector lead adjacent to the package
body.
(2) I C — Continuous (MTBF > 10 years).
