MMIC wideband amplifier

8. Application information

Figure 1 shows a typical application circuit for the BGA2802 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 location of the 470 pF supply decoupling capacitor (Cdec) can be precisely chosen for

optimum performance.

The PCB top ground plane, connected to pins 2, 4 and 5 must be as close as possible to

the MMIC, preferably also below the MMIC. When using via holes, use multiple via holes

as close as possible to the MMIC.

The MMIC is very suitable as IF amplifier in e.g. LNB’s.

The excellent wideband characteristics make it an easy

building block.
