Analog Devices' silicon SPDT switch cuts size and power consumption in cellular radio RF front ends

Analog Devices Inc (ADI) of Norwood, MA, USA (which provides ICs for analog and digital signal processing applications) has launched a high-power (44W peak) single-pole, double-throw (SPDT) silicon switch that enables designers to reduce hardware size and bias power consumption in cellular radio systems.

As the next generation of 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, notes the firm.

Housed in a small 4mm × 4mm LFCSP SMT package, the new ADRF5130 switch meets these requirements through a high level of integration that eliminates the need for external components, says ADI. The switch also reduces power consumption to more efficient levels by operating on a single low-voltage supply with low current consumption compared with existing pin-diode-based solutions, it is claimed.

The ADRF5130 is specified at 0.7-3.5GHz frequency band with typical 0.6dB insertion-loss, high isolation of 50dB, linearity of +68dBm and peak power handling of 44W during continuous operation mode. The device features robust 2000V electro-static-discharge (ESD) protection on all device pins. It also incorporates a fast CMOS-compatible control interface with switching time of less than 1µs. Additionally, a symmetrical circuit architecture allows the RF inputs to be used interchangeably in high-power applications.

The ADRF5130BCPZ is available as samples now, and will be in full production in July, priced at $10.04 each in 1000-unit quantities. The ADRF5130-EVAL-Z evaluation board will be priced at $99.
