Wide Instantaneous Bandwidth High-Efficiency Power Amplifier Applications: SKY66399-11


The SKY66399-11 is a high-efficiency fully input/output matched power amplifier (PA) with high gain and linearity. The compact 5 x 5 mm PA is designed for FDD and TDD 2G/3G/4G LTE small-cell base stations operating from 1900 to 2000 MHz. 

The active biasing circuitry is integrated to compensate PA performance over temperature, voltage, and process variation. The SKY66399-11 is part of high-efficiency, pin-to-pin compatible PA family supporting all 3GPP bands. 

Additional Product Features Include:

  • High-efficiency: PAE = 34% @ +28 dBm (CW)
  • High linearity: +28 dBm with < -50 dBc ACLR with pre-distortion (40 MHz LTE, 8.5 dB PAR signal)
  • High gain: 36.5 dB
  • Excellent input and output return loss: to 50 Ω system
  • Integrated active bias: performance compensated over temp
  • Integrated enable On/Off function: PAEN = 1.7 to 2.5 V
  • Single supply voltage: 5.0 V
  • Pin-to-pin compatible PA family supporting all 3GPP bands
  • Compact (16-pin, 5 x 5 x 1.3 mm) package (MSL3, 260 °C per JEDEC J-STD-020)
