The SHF BT45R bias tee is the RoHS compliant successor of the SHF BT45. It outputs the superposition of the signals applied to the AC and to the DC port. Any existing DC contentis blocked from its AC input while the DC input is practically only allowing transmission of pure DC .Based on SHF’s air line construction, it offers resonance-free transmission up to 45 GHz. In addition to the low insertion loss, all products have an extremely low group delay ripple.
