Abstract
A temperature compensation attenuator comprises a base, a serial film thermistor and a parallel film resistor on the base, an input terminal and an output terminal which are connected to the serial film thermistor The serial film resistor is at least partially a film thermistor and the parallel film resistor is not a thermistor. The attenuators can be applied in various circuits and systems utilizing high frequency waves or microwaves, and more particularly, are suitable for use in mobile communication systems, satellite communication systems, satellite navigational systems, and radar systems which require strict temperature characteristics.
