Skyworks Solutions, Inc. 50-600 MHz, 12 dB 100 Ω Differential Digital Attenuator SKY12407-321LF

Please note: SKY12407-321LF is being discontinued and is not recommended for new designs.

The SKY12407-321LF is a GaAs pHEMT two-bit attenuator I/C. The device is provided in a 3 x 3 mm 12-pin Quad Flat No-Lead (QFN) package.
The SKY12407-321LF is particularly suited for 100 Ω differential systems for which high attenuation accuracy, low insertion loss, and low intermodulation products are required.
The attenuator’s differential input and output impedance is 100 Ω. The device is controlled by two positive DC voltage control pins. The differential attenuator paths are controlled together and can be in either an insertion loss or a 12 dB attenuation state. In a differential system, the attenuator presents a 100 Ω impedance, but can be used as two single-ended attenuators, each with a 50 Ω impedance.
