MMIC wideband medium power ampliﬁer	BGA6489

Figure 2 shows a typical application circuit for the BGA6489 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 the tables below. Capacitors C1 and C2 are used in conjunction with L1 and C3 to fine tune the input and output impedance. For optimum supply decoupling, a 1 μF capacitor (C5) can be added. 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.
