Package Information Plastic Package Case 318M (SOT-343) Ordering Information Device Marking Package MBC13900T1 900 SOT-343 The MBC13900 is a high performance transistor fabricated using Motorola’s 15 GHz fτ bipolar IC process. It is housed in the 4-lead SC-70 (SOT-343) surface mount plastic package resulting in a parasitic effect reduction and RF performance enhancements. The high performance at low power makes the MBC13900 suitable for front-end applications in portable wireless systems such as pagers, cellular and cordless phones. • Low Noise Figure, NFmin = 0.8 dB (Typ) @ 0.9 GHz, 2.0 V and 5.0 mA • Maximum Stable Gain, 22 dB @ 0.9 GHz, 2.0 V and 5.0 mA • Output Third Order Intercept, OIP3 = 18 dBm (Typ) @ 2.0 V and 5.0 mA • Ultra small SOT-343 Surface Mount Package • Available Only in Tape and Reel Packaging %&'( $ )*+,,(- " # )*+,,(- ! ./00(1,/- Figure 1.
