Skyworks Low Noise Amplifiers, Transistors and Drivers ADC Receive Digital Baseband Out Q RRxx IF AGC LNA LNA ADC I Transmit Typical Receiver Block Diagram Skyworks new Low Noise Amplifier (LNA) products meet the Skyworks discrete packaged transistors have the flexibility to be demanding ultra low noise figure and high linearity needs of used in numerous low noise applications. The SKY65050-372LF and todays receiver designs. Fabricated from Skyworks advanced SKY65052-377LF are 200 m pHEMTs designed for low power pseudomorphic high electron mobility transistor (pHEMT), applications operating with a bias as low as 2 V, 5 mA. The silicon germanium (SiGe), and Heterojunction Bipolar Transistor SKY65052-372LF and SKY65051-377LF are 400 m pHEMTs (HBT) processes, these amplifiers have the flexibility to achieve designed for high linearity, low noise applications. Skyworks the necessary gain and linearity specifications. The LNA offers recommended matching networks for unconditional product lineup features a family of two-stage cascaded LNAs, stability up to 18 GHz and the design tools necessary to easily discrete packaged transistors, and high linearity low noise design custom matching networks. driver amplifiers. Skyworks low noise driver amplifiers are ideal choices for The SKY65048-360LF, SKY65049-360LF, and SKY65066-360LF mid-stage amplification in receiver designs. The devices feature complete the family of two-stage LNAs operating over the flat gain response, 2 dB noise figure, and high linearity 0.71.2 GHz, 1.72.4 GHz, and 2.32.7 GHz frequency performance. Devices require minimal external components to bands. The devices integrate the interstage matching simply the design and lower overall cost. network on die to reduce the number external components For more information and our latest product offering (including required.
