What you want is called an isolator. This is a
circulator with the required RF load already attached.
Telewave makes some that will work in the 2-meter ham

If you need remote functionality, the NHRC-4 is a dual port controller so you can connect two radios to it. It's about 3"x 3.75". The partial kit is $40 and the other parts run about $35 to $40, so it can be put together for $75 to $80. It's a nice product. Here's a link;
