ARF1203Q2 is a 37—40 GHz low noise amplifier / driver amplifier designed for high data-rate applications. With 20.5 dB of linear gain, 4 dB noise figure, and low-current operation, it is well suited to demanding, high-order modulation schemes such as millimeter-wave 5G. The circuit draws 40 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.
