Reduce size & power consumption in cellular radio RFFEs

Analog Devices has introduced a high power (44W peak) SPDT silicon switch that enables designers to reduce hardware size and bias power consumption in cellular radio systems. As next-gen communications infrastructure trends toward higher data capacity, cellular radio front ends must scale down in size and provide faster speeds to meet the demands of increased data usage.

ADI’s ADRF5130 switch meets these requirements through a high level of integration that eliminates the need for external components. The switch also reduces power consumption to more efficient levels by operating on a single low-voltage supply with extremely low current consumption compared to existing pin-diode-based solutions. The ADRF5130 is manufactured using silicon technology and is housed in a small 4x4mm LFCSP SMT package.

The ADRF5130 is specified at 0.7 to 3.5GHz frequency band with typical 0.6dB insertion-loss, high isolation of 50dB, excellent linearity of +68dBm and peak power handling of 44W during continuous operation mode. The device features robust 2kV ESD protection on all device pins. It also incorporates a fast CMOS-compatible control interface with switching time less than 1µs. Additionally, a symmetrical circuit architecture allows the RF inputs to be used interchangeably in high power applications.

The ADRF5130, priced at $10.04 each in 1,000 unit quantities, is sampling now will full production scheduled for July 2016.
