DESCRIPTION
Silicon Monolithic Microwave Integrated Circuit (MMIC)
wideband medium power amplifier with internal matching
circuit in a 4-pin SOT89 plastic low thermal resistance
SMD package.
The BGA6x89 series of medium power gain blocks are
resistive feedback Darlington configured amplifiers.
Resistive feedback provides large bandwidth with high
accuracy.
