MGA-30316 3.3 -3.9GHz ½ Watt High Linearity Amplifier
Data Sheet
Description
Avago Technologies’ MGA-30316 is a high linearity ½ Watt PA with good OIP3 performance and exceptionally good PAE at p1dB gain compression point, achieved through the use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process. The device required simple matching components to achieve wide bandwidth performance since it has a built in input prematch. The adjustable temperature compensated internal bias circuit allowed the device to be operated at either class A or class AB operation The MGA-30316 is housed inside a standard 16 pin QFN 3X3 package.
Applications
• Class A driver amplifier for WiMAX Base Stations. • General purpose gain block.

Notes: 4. Measurements at 3.5GHz obtained using demo board described in Figure 6 and 7. 5. 3.5GHz OIP3 test condition: FRF1 - FRF2 = 10MHz with input power of -5dBm per tone measured at worse side band 6. Use proper bias, heat sink and de-rating to ensure maximum channel temperature is not exceeded. See absolute maximum ratings and application note (if applicable) for more details.
