ARF1205Q2 is a 13—25 GHz low noise amplifier / driver amplifier designed for high data-rate applications. With 23 dB of linear gain, 2.5 dB noise figure. The circuit draws 50 mA from a 3.3 V DC supply. The part is internally matched to 50 Ω with ESD protection. RF ports are DC grounded. A VBIAS pin can be connected to the 3.3 V supply, or connected to ground to power down the device.

The part is RoHS* compliant and built with the latest manufacturing techniques for reliability and quality control.
