Description

The RFX8053 is a highly integrated, single-chip, single-die RFeIC

(RF Front-end Integrated Circuit) that incorporates key RF

functionality for IEEE 802.11a/n/ac WLAN systems operating in

the 5.15 to 5.825 GHz range. The RFX8053 architecture

integrates a high-efficiency high-linearity power amplifier (PA), a

low noise amplifier (LNA) with bypass, the associated matching

network, LO rejection, and harmonic filters in a CMOS single-chip

device.

The RFX8053 has simple and low-voltage CMOS control logic that

requires minimal external components. A directional

coupler-based power detect circuit is integrated for accurate

monitoring of output power from the PA.

The RFX8053 is an ultra-compact low-profile 2.5 x 2.5 x 0.45 mm

16-lead QFN package. With support to direct battery operation,

the RFX8053 is an ideal RF front-end solution for implementing

5 GHz WLAN in smartphones and other platforms.

Skyworks Green™ products are compliant with

all applicable legislation and are halogen-free.

Electrical and Mechanical Specifications

The absolute maximum ratings of the RFX8053 are provided in

Table 2. The recommended operating conditions are specified

in Table 3.

The electrical specifications are provided in Tables 4 and 5.

The state of the RFX8053 is determined by the logic provided in

Table 6.

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters

set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. All maximum RF input power ratings assume 50 Ω terminal

impedance.

ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.

This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce

potentials of several kilovolts on the human body or equipment, which can discharge without detection.

Industry-standard ESD handling precautions should be used at all times.

For normal operation of the RFX8053, VDD must be continuously applied to all VDD supply pins.

If control voltage can exceed 1.8 V, a 1 kΩ to 10 kΩ series resistor is recommended for the application circuit on each control line.

Thermal measurements were performed on a test EVB under typical use conditions. Please contact Skyworks for details regarding the test conditions and the configuration of the thermal vias on

the EVB. Refer to the PCB Land Pattern in Figure 3 for recommended thermal vias.
