Analog Devices Silicon SPDT Switch Delivers Fast Settling Time for Demanding Test and Measurement Applications
20 Mai 2015 - 2:00PM
Business Wire
Analog Devices, Inc. (ADI) today 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
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. These advantages include a
settling time that is one hundred times faster than GaAs, robust
ESD (electro-static discharge) protection (2000 V vs. 250 V
compared to GaAs), and the ability to extend the switch’s low
frequency-end one thousand times lower than GaAs while maintaining
high linearity.

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. The HMC1118LP3DE 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. The
combination of features suits the switch for demanding test and
measurement, automated test equipment, defense electronics, and
wireless communication applications as a lower cost alternative to
legacy GaAs switches.
