WiFi front end module eliminates need for LDO regulator
Skyworks has introduced an integrated, 5GHz 802.11ac/n front-end module for mobile platforms including smartphones and tablets. The matched SKY85716-11 FEM incorporates a 5GHz single-pole, double-throw transmit/receive switch, a 5GHz low noise amplifier with bypass and a 5GHz power amplifier. Its 0.33mm package height makes it suitable for low profile SiP modules in embedded systems.
Direct to battery 3 to 5V operation eliminates the need for an LDO regulator, reducing overall BOM costs. The SKY85716-11 meets tough linearity targets with 17.5dBm MCS7 and 16dBm MCS9 output power at 3.3V. An integrated power detector with 20dB of dynamic range is included to provide closed-loop power control within the system. It also features high power mode and power save mode to provide further current saving when operating under lower power.
The device is provided in a compact, 16-pin, 2.3x2.3x0.33mm QFN package. Samples and evaluation boards are available, and pricing depends on quantities.
