MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
The RF Line
NPN Silicon
Low Noise Transistors
silicon bipolar transistors. This device has two 941 die housed in the high
performance six leaded SC–70ML package; yielding a 9 GHz current
gain–bandwidth product.
suited for low–voltage, low–current, front–end applications such as paging,
cellular, GSM, DECT, CT2 and other portable wireless systems. The MRF2947
is fully ion–implanted with gold metallization and nitride passivation for
maximum device reliability, performance and uniformity.
(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
(2) I C — Continuous (MTBF > 10 years).
