The RF Line
NPN Silicon Low Noise Transistors
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)
