Applications WiMAX, WCDMA, and LTE base station receivers Ultra Low Noise Amplifiers (LNAs) Select LNAs Available from Stock for Prototype or High-Volume Production WLAN enterprise access point receivers GPS receivers Skyworks Solutions offers a select group of ultra low noise, high linearity low noise amplifiers which are in stock and ready for immediate design into your demanding Public safety radios applications. Test and measurement instrumentation Pseudomorphic High Electron Mobility Transistor (pHEMT) Linear LNAs ISM band receivers The ultra low noise SKY67100, SKY67101, and SKY67102 are part of a LNA family Military which cover a frequency range from 4002800 MHz, using a common package and communications application layout. The cascode architecture of these devices yields excellent linearity, bandwidth, and super low noise figure with high efficiency. Typical bias conditions are Smart energy V = 4 V and I = 55 mA to produce 17 dB gain across the 4002800 MHz band. A key DD DS attribute of these devices is their high active reverse isolation which results in easy input Features and output impedance matching, and unconditional stability up to 18 GHz and beyond. Excellent noise figure, Additionally, these devices feature fully integrated active bias circuitry requiring only a as low as 0.50 dB single positive supply voltage, resulting in a minimal number of external components. High third order For less demanding applications, the low cost and lower gain SKY67014-396LF features intercept noise figure <1.0 dB, 12 dB gain, 15 dBm OP , yet draws only 5 mA of current with 1 dB Excellent stability 3.3 V supply. An OIP3 of 26 dBm 2.5 GHz is achievable with 15 mA supply current. Integrated active bias circuitry reduces external matching requirements and enables a wide Small form factor packages supply voltage range of 1.8 to 5 V and operation over a broad 15003000 MHz frequency range. For lower frequency operation with similar performance attributes, Skyworks now Broadband designs offers the SKY67012-396LF (300600 MHZ) and the SKY67013-396LF (6001500 MHz). Low supply current All these parts are ideal for use in high sensitivity battery-operated receivers. High efficiency The higher linearity SKY6700X family consists of three devices which cover a frequency range of 7003000 MHz. These cascode pHEMT devices are essentially higher power Flat gain response versions of the SKY67101, SKY67100, and SKY67102 devices with the addition of a low Single and two stage current power down pin. Using larger FET devices, these parts are ideal for operating in designs high temperature environments up to +100 C and provide OIP3 > 39 dBm.The high gain SKY67105, SKY67106, and SKY67107 WiFi LNAs devices utilize the best properties of low noise pHEMT Skyworks offers a broad portfolio of LNAs supporting input stages and inGap HBT or pHEMT output stages multiple WiFi markets, ranging from access points, to obtain excellent noise figure and efficient linearity. gateways, and routers to smart phones and tablets. With These two stage designs achieve outstanding isolation industry-leading low noise figures in the 5 GHz band, the and stability with high gain of roughly 35 dB. With SKY65404-31 is a small form-factor, highly-integrated their extremely high reverse isolation, these devices are LNA ideal for applications requiring excellent receiver unconditionally stable to 24 GHz and beyond. sensitivity. The corresponding device for the 2.4 GHz frequency band is the SKY65405-21, with a matched Applications include high performance cellular noise figure of 1.1 dB. Both are packaged in a infrastructure base station receivers for GSM, WCDMA, 1.5 x 1.5 x 0.45 mm QFN package, and require a minimal and LTE modulation schemes, as well as any other high number of external components, enabling ease-of-use performance LNA application in the 3003000 MHz and a fast time-to-market. frequency range. These devices come packaged in a 2 x 2 mm, 8-pin, plastic DFN package or a 4 x 4 mm, 16-pin QFN package which offers excellent thermal performance.
