August 11, 2020 - Irvine, California - To meet the challenging requirements of cellular LTE and 5G NR infrastructure applications, Skyworks has released the SKY67183−396LF and SKY67189−396LF low noise amplifiers (LNAs). These LNAs feature ultra low-noise figure, exceptional linearity, and operate over a wide range of frequencies. To reduce PCB board space, these devices are housed in an ultra-compact 2 x 2 mm plastic surface mount package. The SKY67183−396LF and SKY67189−396LF are ideal for 2G/3G/4G/5G TDD and FDD infrastructure applications, including small cell, massive MIMO, and macro base stations.


Designed for FDD and TDD 4G LTE and 5G NR systems

  • Low-noise amplifier:
    • Very low noise figure
    • Temperature and process-stable active bias up to +115 °C
    • Wide operating voltage range
    • Low gain slope over operating band
    •  Excellent input return loss
  • Integrated controller:
    •  Stable amplifier bias
    • Temperature compensation
    • True logic level thresholds
    • Fast response time
  • Excellent broadband flat gain performance

About RF Cafe

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
