I am adapting a minimal design based on the TTN Generic Node. I am trying to reduce the BOM and do not require the option to switch power. In the following diagram there are 4 RF signal I/O pins, 2 for RX and 2 for TX:
RFI_P: Positive differential input (RX+, 100Ω).
RFI_N: Negative differential input (RX-, 100Ω).
RFO_HP: Low power output (TX, 50Ω).
RFO_LP: High power output (TX, 50Ω).
There is an internal "power amplifier" supplying from pin VR_PA.
These all feed into a matching circuit that has two switches(U6B and U7).
If I remove the switches and thus circuitry marked in red highlighter, would this have any impact on the performance of the circuit?
