APPLICATIONS Wireless communications General-purpose radio frequency (RF) switching Dual-band applications High speed filter selection Digital transceiver front-end switches IF switching Tuner modules Antenna diversity switching GENERAL DESCRIPTION The ADG904-EP is a wideband analog 4:1 multiplexer that uses The device has on-board CMOS control logic, which eliminates a CMOS process to provide high isolation and low insertion the need for external control circuitry. The control inputs are both loss to 1 GHz. The ADG904-EP is an absorptive/matched mux CMOS and LVTTL compatible. The low power consumption of with 50 terminated shunt legs . This device is designed such this device makes it ideally suited for wireless applications and that the isolation is high over the dc to 1 GHz frequency range. general-purpose high frequency switching. The ADG904-EP switches one of four inputs to a common Additional application and technical information can be found output, RFC, as determined by the 3-bit binary address lines in the ADG904 data sheet. A0, A1, and . A Logic 1 on the pin disables the device. EN EN PRODUCT HIGHLIGHTS 1. 37 dB off isolation at 1 GHz. 2. 1.1 dB insertion loss at 1 GHz. 3. 20-lead LFCSP package. Rev.
