Motorola introduces its sixth generation of RF power transistors for GSM, EDGE, CDMA, and WCDMA base station amplifiers. These RF LDMOS devices help develop low cost, efficient cellular base stations for voice, data, and video transmissions. At 2.2 GHz, typical performance for a 90 watt (P1dB) device is: WCDMA output power is 17 watts; large signal gain is 17 dB; efficiency is 28.5%; and IM3 is 37 dBc.
