SKY12349-362LF分立半导体产品的二极管-可变电容（变容器可变电抗器）规格书PDF中文资料

SKY12349-362LF属于分立半导体产品的二极管-可变电容（变容器可变电抗器）。由美国思佳讯公司制造生产的SKY12349-362LF二极管 - 可变电容（变容器，可变电抗器）可变电容二极管可按照电子可变电容器用途进行生产和分类，并且广泛用于调谐和频率合成应用。虽然大多数二极管的结电容都随着所施加的反向偏压增加而减小，并且能够用作可变电容二极管，但专门作为此类器件销售的产品在生产和分类时特别考虑了这种用途。

描述 Description

The SKY12349-362LF is a GaAs FET five-bit digital attenuator I/C

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

4 x 4 mm, 24-pin Quad Flat No-Lead (QFN) package.

The SKY12349-362LF is particularly suited for applications in

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.
