The matching network is comprised of the following stages:

LT1, CT1: Together with both PCB and device (packaging) parasitics forms a resonant load at the required output frequency.

LT2, CT2: For applications that need to comply with the requirements of ETSI EN 300 220, this network forms a band stop filter resonant at the second harmonic.

CT3 provides a DC block.

CT4, CT5, LT3: Form a low-pass harmonic filter.
