Boxed RF BRIDGE Compared

Evaluation of Ebay Boxed 500kHz-2500 MHz RF Return Loss Bridge with comparisons to the Mini-Circuits ZFDC-20-5 Direction Coupler used as a Return Loss Bridge, a $45 Boxed RLB and the $15 046 PCB bridge that I recently purchased on Ebay. Please note that the performance shown may not fully represent the capability of these RLB's since I am not using 40dB Precision Reference loads or attenuators in this video since I do not have any available. I am using surplus Mil Spec loads however. These should provide better than 20dB return loss with most providing 25-30dB over the 0-1500 MHz frequency range of the DSA815-TG. I would recommend either of these RLBs for use below 500 MHz or so with the Boxed unit being the best performer from 500-1500 MHz.
