2.1GHz 5W GaN Doherty Power Amplifier

RTP21005-11

RFHIC telecommunications amplifier model RTP21005-11 employs GaN (Gallium Nitride) technology to provide 37dBm of average output power from 2110-2170MHz. With incredible 40% efficiency, this amplifier is the key for current LTE wave of Remote Radio Head (RRH) solutions or outdoor small-cell backhaul equipment. The amplifier is 100 x 50 x 20 mm, and utilizes state-of-the-art GaN-SiC transistors. The RTP21005-11, integrated with Doherty configurations, is 100% RF tested and thermal aged for immediate applications to your telecom applications. A 35dB Gain (typ.) model is also available.
