1) The tantal or MLC (Multi Layer Ceramic) capacitor is optional and for bypassing the AC noise introduced from the DC supply. The ca
pacitance value may be determined by customer’s DC supply status. The capacitor should be placed as close as possible to Vs pin
and be connected directly to the ground plane for the best electrical performance.
2) DC blocking capacitors are always necessarily placed at the input and output port for allowing only the RF signal to pass and blockin
g the DC component in the signal. The DC blocking capacitors are included inside the ALN 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 t
he application frequency.
