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.
Features
High linearity and P1dB
Unconditionally Stable across load condition
Built in adjustable temperature compensated internal
bias circuitry
With prematch - required simple matching

Notes:
1. Distribution data sample size is 500 samples taken from 3 different wafer lots and 3 different wafers. Future wafers allocated to this product may
have nominal values anywhere between the upper and lower limits.
2. Measurements were made on a characterization test board, which represents a trade-off between optimal OIP3, gain, P1dB and PAE. Circuit trace
losses have not been de-embedded from measurements above.
