RF1603A

BROADBAND HIGH POWER SP3T SWITCH

The RF1603A is a single-pole three-throw (SP3T) switch designed for gen-

eral purpose switching applications which require very low insertion loss

and high power handling capability with minimal DC power consumption.

The excellent linearity performance achieved by the RF1603A make it

ideal for use in multimode GSM/EDGE/WCDMA/CDMA applications. The

RF1603A offers very high isolation between the RF ports, providing

greater RF separation between the transmit and receive paths, which is

critical in full-duplex systems. Additionally, RF1603A includes integrated

decoding logic, allowing just two control lines needed for switch control.

The RF1603A is packaged in a very compact 2.5mmx2.5mm, 12-pin,

leadless QFN package.
