RF7411数据手册Qorvo中文资料规格书

描述 Description

Qorvo's RF7411 is a high-power, high-efficiency, linear power amplifier designed for use as the final RF amplifier in 3V, 50 ohm WCDMA mobile cellular equipment and spread-spectrum systems. This PA is developed for UMTS Band 1 which operates in the 1920MHz to 1980MHz frequency band. The RF7411 has a digital control pin which enables a low power mode to reduce amplifier gain at lower power levels. The part also has an integrated directional coupler which eliminates the need for an external discrete coupler at the output. The RF7411 (Band 1) meets the spectral linearity requirements of High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), and Long Term Evolution (LTE) data transmission. The RF7411 is assembled in a 10-pin, 3mm x 3mm module.
