A Novel Transmitting Module Self-Monitoring Protection System Based On MEMS Sensors and Actuators
摘要： Design, fabrication, and measurements of a novel transmitting module self-monitoring protection system are presented in this letter. Such a system is based on micro-electromechanical systems (MEMS) sensors and actuators for monitoring and protecting the microwave amplifier circuit. The transmitting module self-monitoring protection system consists of the RF MEMS switches, the directional coupler, and the MEMS power sensors. When the microwave amplifier circuit is at an abnormal state ("open," "short," or "overload"), the transmitting module self-monitoring protection system can isolate the microwave amplifier circuit out of order and reconfigure the transmitting module into impedance matching within 36 ms. When the microwave amplifier circuit is at the overload state, the error between the set switching power and the actual switching power is less than 9%. The measured results agree well with the theory.

摘要： The paper discusses the influence of higher harmonic components in the measured signal on the measurement uncertainty of RF level when diode power sensors are used. A method is proposed to evaluate the measurement uncertainty of different diode power sensors based on the signal harmonic content.

摘要： TüB?TAK UME has established a new power sensor calibration setup incorporating a monitor power sensor utilizing the direct comparison transfer method for frequencies up to 50 GHz. The system adds to TüB?TAK UME’s existing capability to measure power sensors with type N and 3.5 mm connectors. The new measurement setup was validated using certificate values of power sensors for each working frequency range. Good agreement was found between previous calibration results and those obtained with the new system.

摘要： Industries especially telecommunication and aviation industries require RF power sensor calibration. Research Center for Metrology (RCM) – LIPI as National Metrology Institute of Indonesia is responsible to establish RF power sensor calibration. The RF power sensor calibration system in the frequency range of 10 MHz to 18 GHz has been established at RCM - LIPI to build the measurement traceability of RF power sensor in Indonesia. Modification to the conventional direct comparison transfer method has generated more accurate measurement results. Currently, the calibration system is already used to calibrate RF power sensors from calibration laboratories and industries in Indonesia.
