RF3628

Dual Band 3G Power Amplifier

The RF3628 broad-band linear power amplifier supports B1 (1920-1980MHz), B2 (1850 - 1910MHz), B5 (824 - 849MHz) and B8 (880 - 915MHz) in 3.4 V, 50 Ω mobile equipment designed for 3G UMTS transmit. RF3628 meets the spectral linearity requirements of HSDPA, HSUPA and HSPA+ with high power added efficiency. RF3628 can also support narrowband LTE. One digital control pin selects a high or low power mode to optimize performance and current drain at different power levels. RF3628 integrates a directional coupler that eliminates the need for an external discrete couple
