I'm planning on using: https://www.minicircuits.com/pdfs/DCW-30-272+.pdf For the external termination resistor, should I use a 50 Ω resistor? I'm feeding 30 dBm @ 1.4 GHz into pin 1 (input), so, should I see ≈ 29.87 dBm at pin 6 (output) and 2.4 dBm at pin 3 (coupled)

Output powers are correct, however you may experience loss due to microstrip lines.
