8. Application information

Figure 1 shows a typical application circuit for the BGA2716 MMIC. The device is

internally matched to 50 , and therefore does not need any external matching. The value

of the input and output DC blocking capacitors C2 and C3 should not be more than 100 pF

for applications above 100 MHz. However, when the device is operated below 100 MHz,

the capacitor value should be increased.

The nominal value of the RF choke L1 is 100 nH. At the frequencies below 100 MHz this

value should be increased. At frequencies above 1 GHz, a lower value can be used to

tune the output return loss. For optimal results, a good quality chip inductor or a

wire-wound SMD type should be chosen.

Both the RF choke and the 22 nF supply decoupling capacitor C1 should be located as

close as possible to the MMIC.

The printed-circuit board (PCB) top ground plane, connected to pins 2, 4 and 5 must be as

close as possible to the MMIC, and ideally directly beneath it. When using via holes, use

multiple via holes, located as close as possible to the MMIC.
