The SKY12230-12LF is a current-controlled variable attenuator from Skyworks series of high 3rd Order Input Intercept Point (IIP3) components. The device has been designed to operate over the 1.7 to 2.3 GHz frequency band, but is specifically optimized for use as a wide dynamic range, low distortion attenuator. The SKY12230-12LF provides monotonic attenuation performance over its entire control current range. This attenuator is comprised of a pair of matched PIN diodes that terminate two ports of its internal 90-degree hybrid coupler. The diodes are biased using an external control current signal. The attenuator operates with a control current range of 0 to 1.3 mA.
