RF3158PCBA-41X Datasheet PDF - RF Micro Devices

Product Description
The RF3158 is a high power, dual-mode amplifier module with integrated power control. The input and output terminals are internally matched to 50Ω. The amplifier devices are manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (GaAs HBT) process, which is designed to operate either in saturated mode for GMSK signaling or linear mode for 8PSK signaling. The module isdesigned to be the final amplification stage in a dual-mode GSM/EDGE mobile transmit lineup operating in the 824MHz to 915MHz (low) and 1710MHz to 1910MHz (high) bands (such as a cellular handset).
