JFW has recently added four new models to their website. They are conduction cooled (bolt down) type 50 Ohm terminations. The enclosure is flanged with four mounting holes so it can be bolted down to a cooling plate or heatsink. The terminations are available with SMA or N type connectors.

Model 50T-686:  100 Watts average | DC to 3 GHz

Model 50T-687:  100 Watts average | DC to 6 GHz

Model 50T-688:  200 Watts average | DC to 3 GHz

Model 50T-689:  200 Watts average | DC to GHz
