Micro-ESR Oil Condition Sensor
 |
Active Spectrum, Inc.'s Micro-ESR Oil Condition Sensor is an on-vehicle, embedded sensor that accurately measures oxidation, soot, water content and RF dielectric permittivity of engine oil. |
Microwave and MM-wave Tunable filters
High-performance filters are necessary in all real-world communications systems to mitigate interference from adjacent bands. Active Spectrum Inc. is an innovator in the design of low insertion loss, high-rejection, widely tunable filters in the 400 MHz-2.6 GHz bands, 2-18 GHz bands, and more recently for millimeter wave communications for defense applications. The Octave+ Tunable Filter is a miniature 3-pole piezo-tuned filter, rapidly tunable from 8.0 to 12.0 GHz with 250 MHZ BW and insertion loss of -2.0 to -2.5 dB.
