NOTES:
USE SURFACE-MOUNT COMPONENTS FOR OPTIMUM HIGH-FREQUENCY PERFORMANCE.
USE 50 W MICROSTRIP OR STRIPLINE FOR SIGNAL PATHS.
LOCATE 50 W TERMINATIONS AT THE INPUTS OF RECEIVING UNITS.
*C8 IS A RECOMMENDED BYPASS CAPACITOR FOR ADDITIONAL LOW FREQUENCY NOISE FILTERING.
THE SIGNAL DETECT OUTPUT ON THE HFBR-5911L CONTAINS AN INTERNAL 1.8 kW PULL UP RESISTOR. THE OUTPUT STAGE ON THE HFBR5911L IS A PUSH PULL
CONFIGURATION AND THEREFORE DOES NOT REQUIRE AN EXTERNAL PULL UP RESISTOR.
