Phasor Diagrams of Thin Film of LiTaO3 as Applied Infrared Sensors on Satellite of LAPAN-IPB

Abstract Thin film had been manufactured to determine Phasor diagram Thin Film as an application of infrared sensor on the LAPAN IPB satellite. Phasor diagram could be stated as a quantity of vector, which rotated on its starting point that could be described as a vector which its rotational angle was equal to its phase angle on the horizontal axis (X axis). The thin film was manufactured by CSD ( chemical solution deposition ) Method and Spin coating technique with annealing temperature 600 °C and a rotational speed of 3000 rpm for 30 seconds. The test by LCR meter in 600 KHZ – 1 MHZ resulted in value of inductance (L), capacitance (C), resistance (R), and impedance (Z). From the result of LCR metre calculation, Phasor diagram is acquired. The electrical characteristics of thin film LiTaO 3 at 600,700 and 900 kHz frequency have capacitative Phasor diagram, while at 800,1000 kHz frequency it has inductive Phasor diagram. The result of this study is the information of electrical characteristics of thin film LiTaO 3 to support sensor data of satellite sensors.
