8. Application information

Figure 1 shows a typical application circuit for the BGA2715 MMIC. The device is

internally matched to 50 Ω, 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 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.

8.1 Grounding and output impedance

If the grounding is not optimal, the gain becomes less flat and the 50 Ω output matching
becomes worse. Tofurther increase output matching to 50 Ω,a12Ω resistor (R1) can be
placed in series with C3 (see Figure 3). This will significantly improve the output
impedance, at the cost of 1 dB gain and 1 dB output power.
