Not bad at all. Reasonable S11 (<-20dB) up to 800MHz. Tested on 5 units. You probably don't need external terminations above 500MHz anyway. Did not test power rating.
I never received the item, so I can not tell how accurate the description is.... Upon checking the status, I discovered that the seller had canceled the shipment. Also, I had somewhat mysteriously confirmed to have received the item - I NEVER did confirm anything regarding this item... And the seller doesn't reply to my messages, either. So, my advice:: STEAR AWAY FROM THIS SHOP!
