MMIC wideband amplifier)
9. Application information
Figure 1 shows a typical application circuit for the BGM1013 MMIC. The device is
internally matched to 50 and therefore does not need any external matching. Output
impedance is also very good to 75 load. The value of the input and output DC blocking
capacitors C1 and C2 should be not more than 100 pF for applications above 100 MHz.
Their values can be used to fine-tune the input and output impedance.
For the RF-choke, optimal results are obtained with a good quality chip inductor like the
TDK MLG1608 (0603) or a wire-wound SMD. The value of the inductor can be used to
fine-tune the output impedance.
The RF choke and supply decoupling components should be located as close as possible
to the MMIC.
Ground paths must be as short as possible. The printed-circuit board (PCB) top ground
plane must be as close as possible to the MMIC, and ideally directly beneath it. When
using vias, use at least 3 vias for the top ground plane in order to limit ground path
inductance. Supply decoupling with C3 should be from pin 1 to the same top ground
plane.
