ADRF5549BCPZN-R7, RF Front End 1.8 - 2.8GHz LNA + 40W SPDT, Dual channe

ADRF5549 Dual-Channel RF FEMs
Analog Devices Inc. ADRF5549 Dual-Channel RF Front-End Modules (FEMs) are designed for Time Division Duplexing (TDD) applications that operate from 1.8GHz to 2.8GHz. These multi-chip modules are configured in dual-channel with a cascading, two-stage, Low Noise Amplifier (LNA), and a high-power silicon Single-Pole Double-Throw (SPDT) switch. The ADRF5549 FEMs feature high-power handling capacity, low current supply, high-isolation, and low insertion loss. These modules come in a RoHS-compliant, compact 6mm x 6mm dimensions, and 40-lead, Lead Frame Chip-Scale Package (LFCSP). Typical applications include wireless infrastructure, TDD-based communication systems, TDD massive Multiple Input and Multiple Output (MIMO), and active antenna systems.
