BGA6489
MMIC wideband medium power amplifier
Rev. 02 — 15 June 2009 Product data sheet
1. Product profile
1.1 General description
The BGA6489 is a silicon Monolithic Microwave Integrated Circuit (MMIC) wideband
medium power amplifier with internal matching circuit in a 3-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.
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling.
