Merrimac CRM-20-500, 0.1 to 1 GHz, 20 dB, SMA (F), Coaxial Directional Coupler
Dec 17, 2015
Great deal and works as specified
This was a well used coupler but measured just as is specified by Merrimac so the price was great and this works perfectly in my RF system.

10dB Directional Coupler is a great deal
I am an RF Engineer and I need a directional coupler from time to time so I always keep my eye open for a good deal. When I purchased this unit I was skeptical because of the price (it is inexpensive to say the least). But I had to know and once it arrived I tested it on my Network analyzer. It performed as advertised so I purchased a few more. The coupler is well made with 3 SMA connectors. It is just under 4 3/4 inches long and 1 3/8 inches wide. The coupled port is 10dB with a few spots at 11dB between 800MHz and 2500MHz. So flatness is within 1.4dB across the advertised range. Insertion Loss was measured to be 0.5dB across the advertised range.

ZADC 13dB Directional coupler
I purchased this unit because the price was great and it was a new item. I own a wireless lab and I own an HP Network Analyzer and I ran this coupler through all the tests and it is exactly as described. I was so happy with it I purchased more units. Quick and reasonable shipping.
