TEGAM, Inc. released a high power RF calibration system for directional power sensors and RF Wattmeters that is available from virtually all manufacturers including Bird Technologies. The system operates from 250 kHz to 3 GHz and up to 250 W with combined uncertainty less than 1%. This frequency range covers the ISM, land mobile radio and common mobile phone bands.
 

The TEGAM 2505A temperature controlled coaxial RF feedthrough RF power transfer standard enables the precise measurement of microwave power in the 9 kHz to 18 GHz frequency range. These units are durable, highly accurate, and stable with time and temperature. They are ideal for calibrating RF power sensors from all manufacturers or wherever the most accurate RF power measurement is required.

The TEGAM 2510A temperature controlled coaxial RF feedthrough RF power transfer standard enables the precise measurement of microwave power in the 10 MHz to 50 GHz frequency range. These units are durable, highly accurate, and stable with time and temperature. They are ideal for use as standards wherever an accurate RF power measurement is required. Units are supplied with A2LA accredited ISO17025 NIST traceable calibration data.

TEGAM Inc., a leading supplier of innovative RF power measurements, was awarded Patent No. 8,610,069, "Coaxial to Dual Co-Planar Waveguide Launcher for Microwave Bolometry." This patent describes a new way to construct bolometers, a type of microwave power sensor that uses thermistors, that makes them more accurate and easier to assemble. 

The TEGAM Model 2191A  ± 40 VDC bias adapter was designed to work with TEGAM’s 3525 and 3550 LCR meters to enable accurate testing of electrolytic, tantalum and other polarized capacitors.  The 2191A adapter accepts an external DC bias voltage up to ± 40 VDC to be applied across the test capacitor. Four six inch BNC cables are provided to connect the bias adapter to the LCR meter.
