TGF2021-04-SD

DC - 4 GHz Discrete Power pHEMT

Qorvo's TGF2021-04-SD is a high performance pseudomorphic High Electron Mobility GaAs Transistor (pHEMT) housed in a low cost SOT-89 surface mount package.

The device's ideal operating point for low noise operation is at a drain bias of 5 V and 150 mA. At this bias at 900 MHz when matched into 50 ohms using external components, this device is capable of 16 dB gain, 0.6 dB noise figure and 39.5 dBm output IP3. The combination of high gain, low noise and excellent linearity makes this an ideal component for use in a 3G or 4G receive chain.

The part is lead-free and RoHS compliant. Evaluation boards at 900 MHz are available upon request.
