Broadcom BCM94331CSAX

This module is using the following components...

• Broadcom BCM4331 (BCM4331KML1G [P21],

different chip pkg. from the standard BCM4331KMLG)

• w/ 2 Skyworks SE5515 Dual Band Front End Modules (FEMs)
• w/ 1 Skyworks (SiGe) SE5019T 5GHz Power Amplifier (PA)
• w/ 1 Skyworks (SiGe) SE2598L 2.4GHz Power Amplifier (PA)

• Broadcom BCM20702 rev.A3 Bluetooth SoC (USB)
