Balance Thermocouple Power Sensors

BACKGROUND The National Institute of Standards and Technology (NIST) provides a calibration service for power and energy meters to provide traceability for the over $400 billion annual sales of electricity in the US. Wideband power sensors are needed to modernize the NIST RF AC-DC measurement services and reduce calibration uncertainties at high frequencies associated with impedance mismatch effects.    The National Institute of Standards and Technology (NIST) has a requirement for 2 balance thermocouple sensor and is seeking information from sources that may be capable of providing a solution that will achieve the specifications described below:  The Contractor shall provide one (2) balance thermocouple sensor hat meet the following minimum specifications: A.         LIN 001: Balance thermocouple sensor for DC to 18 GHz 1. Shall contain two thermoelements, and can be used in a null arrangement 2. Shall have the frequency range DC to 18 GHz 3. Power range of -35 to +20 dBm 4. Connector N-type, male 5. Maximum input RF power:  for CW signal: 316 mW/+25 dBm at 50 Ohm impedance and for Modulated Pulse Signal: 15 W/+42 dBm (2 microsecond) 6. Maximum input DC power: 316 mW/+25 dBm 7. Typical load resistance measured at the coaxial connector of 50 Ohms 8. Typical DC heater resistance measured at the DC connector of 50 Ohms 9. Thermocouple resistance: Single (RF side: 8 kOhms) and Dual (RF and DC: 16-17 kOhms 10. Thermocouple sensitivity for RF connector at 25 C: 1070 mV/W; DC Connector at 25 C: 1050 mV/W 11. Delivered with calibration with a calibration factor uncertainty of not more than 1.75 % at 18 Ghz 12. SWR of not more than 2.0 at highest frequency at the operating temperature 13. One unit with a 5 ft power sensor cable and the other unit with a 10 ft power sensor cable.  B. Balance thermocouple sensor for DC to 50 GHz 1. Shall contain two thermoelements, and can be used in a null arrangement 2. Shall have the frequency range DC to 50 GHz 3. Power range of -35 to +20 dBm 4. Connector 2.4 mm, male 5. Maximum input RF power: for CW signal= 316 mW/+25 dBm at 50 Ohm impedance and for Modulated Pulse Signal=15 W/+42 dBm (2 microsecond) 6. Maximum input DC power: 316 mW/+25 dBm 7. Typical load resistance measured at the coaxial connector of 50 Ohms 8. Typical DC heater resistance measured at the DC connector of about 97 Ohms 9. Thermocouple resistance: Single (RF side: 8 kOhms) and Dual (RF and DC: 16-17 kOhms 10. Thermocouple sensitivity for RF connector at 25 C: 1080 mV/W; DC Connector at 25 C: 2070 mV/W 11. Delivered with calibration with a calibration factor uncertainty of not more than 1.75 % at 50 Ghz 12. SWR of not more than 5.0 at highest frequency at the operating temperature 13.
