APPLICATION INFORMATION  
Figure 2 shows a typical application circuit for the  
BGA2748 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,  
C3 should be not 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 22 nF supply decoupling capacitor, C1 should be  
located as closely as possible to the MMIC.  
Fig.3 Easy cascading application circuit.  
Separate paths must be used for the ground planes of the  
ground pins GND1, GND2, and these paths must be as  
short as possible. When using vias, use multiple vias per  
pin in order to limit ground path inductance.

Figure 3 shows two cascaded MMICs. This configuration  
doubles overall gain while preserving broadband  
characteristics. Supply decoupling and grounding  
conditions for each MMIC are the same as those for the  
circuit of Fig.2.

Fig.5 Application as RF amplifier.  
The excellent wideband characteristics of the MMIC make  
it and ideal building block in IF amplifier applications such  
as LBNs (see Fig.4).  
As a buffer amplifier between an LNA and a mixer in a  
receiver circuit, the MMIC offers an easy matching, low  
noise solution (see Fig.5).

In Fig.6 the MMIC is used as a driver to the power amplifier  
in part of a transmitter circuit. Good linear performance  
and matched input and output offer quick design solutions  
in such applications.
