RF7228 Datasheet 3v W-cdma Band 8 Linear Pa Module

Manufacturer: RF Micro Devices (now Qorvo)

Overview: RF7228 3V W-CDMA BAND 8 LINEAR PA MODULE Package Style: Module, 10-Pin, 3mmx3mmx1.

General Description

The RF7228 is a high-power, high-efficiency, linear power amplifier designed for use as the final RF amplifier in 3V, 50 W-CDMA mobile cellular equipment and spread-spectrum systems.

This PA is developed for UMTS Band 8 which operates in the 880MHz to 915MHz frequency band.

The RF7228 has two digital control pins to select one of three power modes to optimize performance and current drain at lower power levels.

Key Features
