Product ReviewsMini Circuits 5-1000MHz 10dB Directional Coupler ADC-10-4 with designed PCB

Good but no free P&H

The coupler works. Not surprising because it is a quality product from Minicircuits with good isolation and clear spec's. I tested it with a 10dB attenuator and return loss was 20dB as it should. The bridge measures power coming from input so if you want measure return power from load, swap input and output.
But the postage and handling are not free. Total price is still good, IMO.
You need a 50 ohms SMD resistor, too. I used a 52R 0630. If you want neat connections buy SMA edge connectors too. Connectors for thinner, 1mm, PCB are best. They can be bought here or elsewhere.Read full review...
