The PMA3-5123+ is a pHEMT-based ultra-low noise MMIC amplifier with high IP3 and flat gain. Operating from 5.5 to 12.5 GHz, this amplifier features high dynamic range with typical 1.0 dB noise figure, 21.6 dB gain, +16.8 dBm P1dB, and +28.1 dBm OIP3. This combination of characteristics makes it ideal for sensitive, high dynamic range receiver applications. The device is internally DC blocked, and a DC path to ground is present at the RF input and output ports for ESD protection. PMA3-5123+ operates on a single +4 V supply, is well matched to 50Ω, and comes in a small, low profile 3x3 mm QFN-style package for easy integration into dense circuit board layouts.
