Applications
The LX5589H is designed for 802.11ac (Wi-Fi 5) access points, routers, and IoT gateways operating in the 5 GHz UNII bands, where high throughput and spectral efficiency are required. Its integrated front-end architecture enables compact PCB layouts in enterprise access points, residential gateways, and dual-band Wi-Fi range extenders without separate discrete amplifiers. The module is also well suited for embedded Wi-Fi modules in smart TVs, set-top boxes, and industrial wireless bridges targeting 80 MHz and 160 MHz channel operation.

Frequently Asked Questions
Which frequency band does the LX5589H cover, and which 802.11 standard does it support?
The LX5589H operates across the 5.15 GHz to 5.85 GHz range, covering all UNII-1, UNII-2, and UNII-2-Extended sub-bands used by 802.11ac (Wi-Fi 5). This 700 MHz span supports 20 MHz, 40 MHz, 80 MHz, and 160 MHz channel widths specified in the 802.11ac standard for maximum throughput in crowded wireless environments.
What functions are integrated inside the LX5589H, and how does this reduce external component count?
The LX5589H integrates a power amplifier, low-noise amplifier, and RF transmit/receive switch in a single QFN die, eliminating the need for 3 to 5 discrete RF components and associated matching networks. This integration can shrink the RF front-end PCB footprint by more than 50% compared to a discrete implementation, reducing assembly cost and simplifying certification of Wi-Fi modules.
How should a PCB designer handle RF layout around the LX5589H to maintain its rated noise figure?
For optimal noise figure — typically around 2 dB to 3 dB for this class of LNA — the antenna trace from LX5589H should be kept below 10 mm, use 50 Ω controlled-impedance microstrip, and be routed away from digital switching lines on adjacent layers. Decoupling capacitors of 100 nF and 10 nF should be placed within 0.5 mm of each supply pin to suppress VCC noise that degrades amplifier linearity and EVM.
In which end products is the LX5589H commonly designed in, and what makes it suitable for those markets?
The LX5589H is commonly integrated into 802.11ac dual-band routers, enterprise access points, and Wi-Fi 5 module cards. Its 5.15 GHz to 5.85 GHz coverage, single-chip front-end, and QFN form factor allow OEMs to certify a single RF module that meets FCC, CE, and MIC regulations across 8 UNII channels, reducing time-to-market versus a discrete RF design.
