AT02M750.07 - Page 1 of 14 Product Family: Temperature Variable Attenuators Part Number Series: ATV1206C Series Construction: Features: High purity Alumina Substrate Thermo-sensitive thermistor Ni alloy thin-film resistive elements 100% matte tin finish terminations (RoHS compliant and Pb Free) 1206 English case size 100mW power rating Attenuation values between 1 and 16dB 0.5dB attenuation tolerance DC to 3GHz High volume production suitable for commercial and special applications The ATV1206C series of temperature variable attenuators utilizes a thermo-sensitive thermistor to control attenuation change over temperature. These are useful in replacing temperature compensation circuits and can simplify auto gain control (AGC) and circuit design in power amplification devices resulting in reduced design time and cost savings.
