The CYW4339XKWBGT is a high performance radio frequency (RF) transceiver IC designed to enable wireless connectivity in the IEEE 802.11a/b/g/n/ac/ax/p standards. The chip is compliant with broadcast and multicast management protocols, providing an optimal solution for battery-powered hotspots and embedded applications. This transceiver IC is designed specifically to minimize power consumption, while still providing features that are typically found in more expensive solutions.

The CYW4339XKWBGT is a fully integrated single-chip transceiver IC with a nominal input of 19 dBm (1.2 GHz). It operates at both 2.4GHz and 5GHz frequency bands and is capable of providing up to 400Mbps data rate for the 802.11ac networks. The integrated power amplifier (PA) offers a maximum transmit power of up to 19 dBm in both bands. The IC also contains a low-noise amplifier (LNA) with a discrete input stage, providing a maximum RF input of –24dBm. The integrated voltage regulator with wide operating range also ensures proper operation.

The CYW4339XKWBGT has several advanced features, including a high performance spread spectrum modem, a multi-stream radio that supports up to three simultaneous spatial streams (3X3 MIMO) for both Transmit and Receive, and a high performance DSP processor for data processing. The integrated PLL, ADC, DAC, and low-noise amplifier further simplify the system design and help to reduce the overall size of the device. The IC also features an on-chip calibration circuitry that can be used for accurate frequency offset measurement and adjustment.

The CYW4339XKWBGT contains a baseband processor that supports many advanced wireless communication features. It supports advanced Quality of Service (QoS) features, such as frame aggregation, frame bursting, and multiple output packet aggregation. The processor also supports automatic packet fragmentation and reassembly. The IC supports enhanced security features, including robust WEP, TKIP, AES security, and authenticated encryption.

The chip is capable of driving industry standard 802.11a/b/g/n/ac/ax/p compatible devices, such as WiFi routers, access points, gateways, femtocells, and wireless bridges. The integrated Voltage Regulator further simplifies the design of power management for the device. The Voltage Regulator is capable of operating over a wide voltage range of 5V to 28V, with improved efficiency when the supply voltage is closer to the nominal range.

In summary, the CYW4339XKWBGT is an advanced, integrated RF transceiver IC for wireless applications that supports the IEEE 802.11a/b/g/n/ac/ax/p protocol standards. The integrated PLL, ADC, DAC, and low-noise amplifier facilitate system design while the integrated power amplifier (PA) and low-noise amplifier (LNA) provide increased transmit power and improved sensitivity, respectively. The integrated chip also contains a baseband processor that supports many advanced features, such asAggregation, Frame Bursting, and multiple output packet aggregation. The Voltage Regulator is capable of operating over a wide voltage range, with improved efficiency when the supply voltage is closer to the nominal range.
