Resistor network in between SAW Filter and Power Amplifier
True the 56pF blocks DC but in some case sizes and brands is optimal for lowest ESR at Series Resonant Frequency (SRF) ((which is often referred to as Self Resonant Freq. however there is also a higher Parallel Resonant Frequency (PRF) which is less commonly known or relevant}}

In SMD603 size certain low cost ceramics , this is the optimal value for low Z DC blocking, as higher values become more inductive and lower values rise above > 10% of 50 Ohms so  this value has the lowest impedance at Self Resonance Frequency (SRF) for some types of ceramics.  

Smaller RF physical capacitor SMD sizes can have higher SRF and different ceramic construction or cost or brands may have different SRF values, so it is wise to compare datasheets before selection and have a second source. 

Then L5 value (8.2nH) is used for impedance matching just under 50 Ohms in combination with RF band filtering.  Caps with DNP are Do Not Populate are optional depending on board ground plane capacitance and L5 self capacitance.

The R Pi network appears to be a 2dB pad.

*(speculation) Depending on Rx input Resistance, there can also be a higher f notch filter with L5 and SRF in case of upper mobile band interference.
