Description

The SKY12340-364LF is a GaAs FET five-bit digital attenuator I/C

with a serial-to-parallel driver. The device is provided in a

5 x 5 mm, 32-pin Quad Flat No-Lead (QFN) package.

The SKY12340-364LF is particularly suited at IF frequencies for

which high attenuation accuracy, low insertion loss, and low

intermodulation products are required.

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.
