MMIC wideband amplifier

BGA2711

APPLICATION INFORMATION

Figure shows a typical application circuit for the 
BGA2711 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.

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 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.

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.
