BGU7224
2.4 GHz ISM SiGe:C low-noise amplifier MMIC with bypass
11.2 Application circuit
In Figure 33 the application diagram as supplied on the evaluation board is given.
Note that in Figure 33 the schematic for the BGU7224 evaluation board is shown using
only two external components. A DC-decoupling capacitor placed close to V
CC
(pin 6) and
a matching shunt inductor at RF_IN.
The BGU7224 can also be used without the matching inductor at RF_IN. However, in this
case the input return loss will be less than 10 dB (approximately 9 dB) at a frequency of
2.4 GHz.
For more details or information please see application note AN11390.

Preferred vendors different from the ones listed can be chosen, but be aware that the performance
could be affected.
