MGA-30889
40MHz - 2600MHz
Flat Gain High Linearity Gain Block
Data Sheet
Description
Avago Technologies’ MGA-30889 is a broadband, flat gain,
high linearity gain block MMIC amplifier achieved through
the use of Avago Technologies’ proprietary 0.25um GaAs
Enhancement-mode pHEMT process.
The device required simple dc biasing components to
achieve wide bandwidth performance. The temperature
compensated internal bias circuit provides stable current
over temperature and process threshold voltage
variation.
The MGA-30889 is housed inside a low cost RoHS
compliant SOT89 industry standard SMT package (4.5 x
4.1 x 1.5 mm).

Applications
Attention: Observe precautions for
handling electrostatic sensitive devices.
ESD Machine Model = 50 V
ESD Human Body Model = 400 V
Refer to Avago Application Note A004R:
Electrostatic Discharge, Damage and Control.
•
IF amplifier, RF driver amplifier
•
General purpose gain block
Note:
1. Enhancement mode technology employs positive gate voltage,
thereby eliminating the need of negative gate voltage associated
with conventional depletion mode devices.

Notes:
1. Distribution data sample size is 3000 samples taken from 3 different
wafer lots. 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 and P1dB. Circuit
trace losses have not been de-embedded from measurements
above.

Notes:
1. Measurements obtained using demo board described in Figure 30 and 31. 40MHz data was taken with 40MHz - 2GHz Application Test Circuit,
900MHz data with 0.2GHz – 2.6GHz Application Test Circuit and 1.95GHz data with 1.5GHz - 2.6GHz Application Test Circuit respectively.
2. OIP3 test condition: F

= 10MHz with input power of -15dBm per tone measured at worse side band.
3. 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.
