Analog Devices Silicon SPDT Switch for test and measurement applications

BANGALORE: Analog Devices, which designs and manufactures semiconductor products and solutions, has introduced an absorptive single-pole, double-throw (SPDT) switch specified for the 9-KHz to 13-GHz frequency band, with high isolation of 48 dB and low insertion-loss of 0.6 dB at 8-GHz operation.

The HMC1118LP3DE is available at Rs $6.18 and it is the first offering within ADI’s new RF and microwave control product portfolio to exhibit the inherent advantages of silicon process technology, which offers critical advantages over legacy GaAs (gallium-arsenide) RF switches, a release said.

The product is applicable for demanding test and measurement, automated test equipment, defense electronics, and wireless communication applications as a lower cost alternative to legacy GaAs switches.

“The HMC1118LP3DE also offers industry-leading RF power handling of 4 W in through and 0.5 W in hot-switching operating modes. Hot-switching power handling is more than two times better than competitive parts with similar RF bandwidth, which allows engineers to increase allowed RF power in their applications and systems without the risk of damage to the part,” it added.

It is optimized for high-isolation and extremely flat transfer characteristics within a wide operating frequency range up to 13 GHz, while maintaining high signal fidelity down to 9 kHz.
