Integrated Passive Device for Semtech SX1261 / SX1262 / LLCC68
▲This application note serves as a guide on the usage and expected performance of Johanson Technology’s impedance-matched filter 0900FM15K0039, designed specifically for the Semtech SX1261, SX1262, and LLCC68 RF transceivers operating at 868 and 915MHz ISM bands – part of their Long-Range Low Power LoRA® and LoRa Smart Home™ product lines.
●Introduction
▲Using Johanson’s integrated passive device (IPD) 0900FM15K0039, overall PCB space and component count can be significantly reduced as illustrated in Figure 3. This IPD’s performance has shown to meet (and in some cases exceed) the original discrete reference design in terms of fundamental and harmonic power.
▲With this device, the entire front end RF matching network is reduced to a single EIA 0805 (2.0mm x 1.25mm) component. It is recommended for applications where PCB space is a priority along with consistency of RF performance over production.
