The BGA6589 is a silicon Monolithic Microwave Integrated Circuit (MMIC) wideband
medium power amplifier with internal matching circuit in a 3-pin SOT89plasticlowthermal
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.

8.Application information
Figure 10 shows a typical application circuit for the BGA6589 MMIC. The device is
internally matched to 50 Ω, and therefore does not require any external matching. The
value of the input and output DC blocking capacitors C1 and C2 depends on the operating
frequency; see Table 9. Capacitors C1 and C2 are used in conjunction with L1 and C3 to
fine tune the input and output impedance. Capacitor C4 is a supply decoupling capacitor.
A 1 µF capacitor (C5) can be added for optimum supply decoupling. The external
components should be placed as close as possible to the MMIC. When using via holes,
use multiple via holes per pin in order to limit ground path induction. Resistor R1 is a bias
resistor providing DC current stability with temperature.
