Internally Matched LNA Module

1) The tantal capacitor is optional and for bypassing the AC noise introduced from the DC supply.

The capacitance value may be determined by customer

’s DC supply status.

2) So-called DC blocking capacitors are always necessarily placed at the input and output port

for allowing only the RF signal to pass and blocking the DC component in the signal. The DC

blocking capacitors are included inside the LNA module. Therefore, C1 & C2 capacitors may

not be necessary, but can be added just in case that the customer wants. The value of C1 &

C2 is determined by considering the application frequency.
