描述 Description

The SKY13421-486LF is a pHEMT GaAs Double-Pole, Double-Throw (DPxDT) switch designed for cellular infrastructure band switching applications. This device is a paired DPDT switch, controlled synchronously, that includes two Single-Pole, Double-Throw (SPDT) switches with RF lines that cross inside the chip. The internal crossed switch arrangement is designed to switch balanced RF filters.

Switching is controlled by a single control voltage. Depending on the logic voltage level applied to the control pin (VCTL), the RFCA and RFCB pins are each connected to one of two switched RF outputs (RF1A, RF1B, RF2A, or RF2B) using a low insertion loss path, while maintaining a high isolation path to the alternate port. DC blocking capacitors are required on all RF ports.

The switch is manufactured in a compact, 1.6 x 1.6 mm, 14-pin exposed pad plastic Quad Flat No-Lead (QFN) package.
