8. Application information
BGA6289_2
Product data sheet
Figure 10
internally matched to 50 , 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
fine tune the input and output impedance. Capacitor C4 is a supply decoupling capacitor.
A 1 F 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.
