The PSPL5370 Pick-off Tee is an ultra-broadband resistive coupler, which provides a scaled (5x or 10x) replica of signals passing through the tee. The device has excellent through-line insertion loss and pick-off ratio stability while operating from DC to 25 GHz. It has good impedance match across a wide range of frequencies, with return loss of 15 dB from 0-25 GHz.
