CHF190104KxBF Series 1 kW Stripline Termination Typical Performance Return Loss (dB) -10.00 -20.00 -30.00 -40.00 -50.00 0.05 1.00 F (GHz) 0.470 GHz -38.48 dB 0.800 GHz -31.83 dB 1.000 GHz -19.53 dB Mounting High Power Devices The mounting surface must be flat to less than 0.0254 mm (0.001 inch) and devoid of scratches or burrs. The underside of the flange should be brushed with thermal grease prior to being fastened to the heat sink with mounting screws. The thermal grease will fill any air gaps and help to keep a good thermal contact. Termination/Resistor Tabs (1 for Termination, 2 for Resistors) Circuit Board Pre-tin the tab prior to installation. Position the tab over the circuit and solder in place. Heat Sink/Ground Plane Flange Ensure that the temperature on the surface of the flange does not exceed 110 ˚C when running at 100 % of load. If the temperature increases then derate the power. REV. 12/15 Specifications are subject to change without notice.
