Description
The SKY12325- 350LF is a three- bit digital attenuator . The
attenuation bits are binary weighted, with the Least Significant Bit
(LSB) equal to 1 dB. States are selected by three positive voltage
control inputs (pins V1, V2, and V3). DC blocking capacitors are
required at each RF port. Both RF ports are absorptive.
The SKY12325- 350LF is provided in a miniature 3 x 3 mm, 16 - pin
exposed pad plastic Quad Flat No - Lead (QFN) package. 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.
