Description  
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.  
A functional block diagram is shown in Figure 1. The pin  
configuration and package are shown in Figure 2. Signal pin  
assignments and functional pin descriptions are provided in  
Table 1.
