Receive (RX) Path
There are two receive modes:
●
Receive LNA:
Additional gain is provided by the LNA: gain = 11 dB, NF = 2. The LNA improves
the sensitivity by approximately 5 dB.
●
Receive Bypass:
The LNA is removed from the RX path.

Filtering (Optional)
No external filtering is needed. However, there are positions to add filter components in case it is
needed.
