ADG904BRUZ-R Description

Short technical summary and product information.

The ADG904BRUZ-R is a reflective 4:1 multiplexer/SP4T RF switch from Analog Devices. It features a wideband -3dB bandwidth of 2.5 GHz, making it suitable for RF applications up to the GHz range. The switch provides high off isolation of 37 dB at 1 GHz and low insertion loss of 1.1 dB from dc to 1 GHz. It operates from a single supply voltage between 1.65V and 2.75V, with a maximum supply current of only 1 µA. The control logic is CMOS/LVTTL compatible, enabling easy interfacing with digital controllers. Switching times are fast: 10 ns on and 16 ns off. This reflective switch (ADG904-R variant) does not have internal 50-ohm shunt termination, unlike the absorptive version. The device is packaged in a 20-TSSOP surface mount package and operates over the industrial temperature range of -40°C to +85°C. Typical applications include wireless communications, dual-band RF front-end switching, high-speed filter selection, and antenna diversity switching.
