Single Voltage E-pHEMT Low Noise 42 dBm OIP3 in LPCC

Currently Viewing:

The ATF-521P8 is a single-voltage high linearity, low noise E-pHEMT housed in an 8-lead LPCC (JEDEC DFP-N) package. The device exhibits exceptional RF performance, power efficiency and product consistency in the 50MHz to 6 GHz frequency range.


  • At 2GHz, the ATF-521P8 delivers high OIP3 of up to 42dBm, P1dB of 26.5dBm and low NF of 1.5dB, requiring only 4.5V/200mA for DC biasing.
  • The thermally efficient package measures only 2mm x 2mm x 0.75mm. Its backside metalization provides excellent thermal dissipation as well as visual evidence of solder reflow. The device has a Point MTTF of over 300 years at a mounting temperature of 85°C
