描述 Description

The SKY13421-486LF is a pHEMT GaAs double-pole, doublethrow

(DPxDT) switch designed for cellular infrastructure band

switching applications. This device is a paired DPDT switch,

controlled synchronously, that includes two single-pole, doublethrow

(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.

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
