- Wide frequency coverage (vs Narrowband RF front ends)
- TDD-optimized design (vs FDD RF front ends)
Design Notes
Ensure proper grounding and thermal management. The exposed pad of the 40-LFCSP-VQ package must be soldered to a ground plane with multiple thermal vias to dissipate heat effectively. Follow the layout guidelines in the ADRF5545A datasheet for optimal RF performance.
Keep RF traces as short as possible and use controlled impedance transmission lines (e.g., 50 ohms) for RF1_IN, RF1_OUT, RF2_IN, and RF2_OUT. Maintain adequate spacing between RF lines and digital control lines to minimize coupling.
Ensure the TDD_SW pin is properly synchronized with the system timing to prevent signal leakage between transmit and receive paths. Incorrect switching can degrade performance and cause spurious emissions.
