The ADRF5515 is a dual-channel, integrated RF, front-end, multichip module designed for time division duplexing (TDD) applications. The device operates from 3.3 GHz to 4.0 GHz. The ADRF5515 is configured in dual channels with a cascading, two-stage, LNA and a high power silicon SPDT switch.
The ADRF5515 is pin-compatible with the ADRF5545A, 10 W version, which operates from 2.4 GHz to 4.2 GHz. The ADRF5515 does not require any matching components at the RF ports that are internally matched to 50 Ω. The ANT and TERM ports are also internally ac-coupled. Therefore, only receiver ports require external dc blocking capacitors. The device comes in an RoHS compliant, compact, 6 mm × 6 mm, 40-lead LFCSP package.
