Marki high isolation power combiners feature a unique hand tuned construction that allows typical isolation of better than 30 dB from kHz to microwave frequencies. The have a nominal insertion loss of 6 dB and are suited for any application that requires high isolation power combining, including two-tone measurements and combining of signals with dramatically different power levels.

Electrical Specifications - Specifications guaranteed from -55 to +100°C, measured in a 50Ω system.
