ADL5321:  2.3 GHz TO 4.0 GHz ¼ Watt RF Driver Amplifier

Product Details

Product Status:Recommended for New Designs

The ADL5321 is a broadband, linear driver RF amplifier that operates at frequencies from 2.3 GHz to 4.0 GHz. The device can be used in a wide variety of wired and wireless applications, including ISM, WLL, PCS, GSM, CDMA, and W-CDMA.

The ADL5321 operates with a 5 V supply voltage and a supply current of 90 mA.

The ADL5321 is fabricated on the GaAs HBT process. The device is packaged in a low cost SOT-89 that uses an exposed paddle for excellent thermal impedance. It operates from −40°C to +105°C, and a fully populated evaluation board is available.

The ADL5320 is a companion part to the ADL5321 that operates at similar performance from 400 MHz to 2700 MHz.


  • Operation: 2.3 GHz to 4.0 GHz
  • Gain of 14 dB at 2.6 GHz
  • OIP3 of 41 dBm at 2.6 GHz
  • P1dB of 25.7 dBm at 2.6 GHz
  • Noise figure: 4.0 dB at 2.6 GHz
  • Power supply: 5 V
  • Power supply current: 90 mA typical
  • Internal active biasing
  • Thermally efficient SOT-89 package
  • ESD rating of ±2 kV (Class 3A)
