Ultra Low Noise Amplifiers (LNAs)

Skyworks Solutions offers a select group of ultra-low-noise, high linearity and versatile RF amplifiers which are in stock and ready for immediate design into your demanding receiver applications.

For Cellular Infrastructure, or any high-performance receiver, these ultra-low-noise SKY67150, SKY67151, and SKY67153 are part of a new LNA family which cover a frequency range from 50–3,800 MHz, using a common 2 x 2 mm DFN package and application layout. The cascode architecture of these pHEMT LNA devices enables high linearity, high gain (26 dB) and super-low noise figure (<0.25 dB). The higher linearity SKY67021-396LF, SKY67022-396LF and SKY67023-396LF devices cover a frequency range of 700–3,000 MHz with OIP3 >40 dBm. The SKY67105, SKY67106, and SKY67107 families offer low NF and high 35 dB gain coupled with very high linearity.

For Broadband Wireless applications, the cost competitive SKY67012, SKY67013, SKY67014 and SKY67015-396LF feature <1.0 dB noise figure and gain that ranges from 12 dB-16 dB with supply current between 5 mA and 30 mA. The unique pHEMT design enables a wide supply voltage range of 1.8 to 5 V and operation from 30–3,000 MHz. Skyworks also offers discrete FETs such as the SKY65050-372LF, and silicon germanium LNAs like the SKY65047-360LF that provide the system designer the ultimate in design flexibility and broadband RF performance.

For WLAN and ISM Band applications, Skyworks offers a series of LNAs supporting multiple Wi-Fi markets and applications. With an industry-leading low noise figure of 1.2 dB at 5 GHz, the SKY65404-31 is a very small form-factor, highly-integrated LNA ideal for applications requiring excellent receiver sensitivity. The corresponding device for the 2.4 GHz frequency band is the SKY65405-21. Both are packaged in 1.5 x 1.5 DFN packages, and require a minimal number of external components, enabling ease of use.
