RFFM8505SQ Description

Short technical summary and product information.

The RFFM8505SQ from RFMD is a highly integrated Front End Module (FEM) designed for 5GHz WiFi 802.11a/n/ac applications. This module simplifies the total front-end solution by minimizing external components, reducing the bill of materials, system footprint, and manufacturing costs.

Key electrical specifications include an output power of 18dBm at 11ac 80MHz and 19.5dBm at 11n 40MHz. It features a 50 Ohm input and output impedance. The module integrates a 5GHz power amplifier (PA), a single pole double throw (SP2T) switch, a low-noise amplifier (LNA) with bypass functionality, and a power detector coupler for enhanced accuracy.

Packaged in a compact 2.5mm x 2.5mm x 0.40mm, 16-pin QFN package, the RFFM8505SQ is suitable for space-constrained designs, including System-in-Package (SiP) and Chip-on-Board (CoB) applications. Its low height profile makes it ideal for mobile devices, tablets, and other consumer electronics where miniaturization is critical.

Applications for this module include cellular handsets, mobile devices, tablets, consumer electronics, gaming devices, netbooks/notebooks, and TV/monitors/video equipment. It meets or exceeds the RF front-end requirements for IEEE 802.11a/n/ac WiFi RF systems.
