ADRF5515BCPZN

ADRF5515 is a dual-channel, integrated RF, front-end, multichip module designed for time division duplexing (TDD) applications. The device operates from 3.3GHz to 4.0GHz. This is configured in dual channels with a cascading, two-stage, LNA and a high-power silicon SPDT switch. In high gain mode, the cascaded two-stage LNA and switch offer a low noise figure of 1.0dB and a high gain of 33dB at 3.6GHz with an output third-order intercept point (OIP3) of 32dBm (typical). In low gain mode, one stage of the two-stage LNA is in bypass, providing 16 dB of gain at a lower current of 36mA. In power-down mode, the LNAs are turned off and the device draws 12mA. Application includes wireless infrastructure, TDD massive multiple input and multiple output and active antenna systems, TDD-based communication systems.
