High Power RF Transfer Standard 250 kHz to 1000 MHz The TEGAM 2601A High Power RF Transfer Standard enables the precise measurement of high power (+34 to +54 dBm) microwave power in the 250 kHz to 1000 MHz frequency range. The TEGAM 2601A working standards is constructed of a directional coupler paired with a 1505A thermistor power standard. The design has the coupler and 1505A mounted on an aluminum heat sink to reduce changes in coupling factor attributable to heating. These standards are highly accurate and stable with time and temperature. They are ideal for use as standards for the transfer of calibration factors to other high power RF standards and power sensors. The calibration of these standards is traceable to the International System of Units (SI) through the National Institute of Standards and Technology (NIST) or other recognized National Metrology Institutes.
