MOTOROLA RF DEVICE DATA
Motorola, Inc. 1997
The RF Line
Motorola’s MRF2947 device contains two high performance, low–noise NPN
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.
The RF performance at levels of 1 volt and 1 mA makes the MRF2947 well
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.
Low Noise Figure, NF = 1.5 dB (Typ) @ 1 GHz @ 5 mA
High Current Gain–Bandwidth Product, ft = 9 GHz (Typ) @ 6 Volts, 15 mA
Maximum Stable Gain, 18 dB @ 1 GHz @ 5 mA
Output Third Order Intercept, OIP3 = +27 dBm
Available in Tape and Reel Packaging Options:
T1 Suffix = 3,000 Units per 8 mm, 7 inch Reel
T2 Suffix = 3,000 Units per 8 mm, 7 inch Reel (reverse device
orientation in tape)
