RF-MEMS Switches Challenge Electro-Mechanical Relays

27 December 2016

Analog Devices, Inc. (ADI) has unveiled a pair of radio-frequency (RF) micro-electro-mechanical system (MEMS) switches aimed at displacing conventional electro-mechanical relays in test instruments, automated test equipment (ATE), and other applications requiring exceptionally wide bandwidth (from DC to as much as 14 GHz), board-space efficiency, low power consumption and long switch life.

Analog Devices' ADGM1304 and ADGM1004 RF-MEMS switches bid to replace electro-mechanical relays in automated test equipment and other applications demanding extremely wide bandwidth.

Image source: Analog Devices, Inc.The first in a new product series, ADI’s ADGM1304 and ADGM1004, are single-pole, four-throw RF MEMS switches housed in ultra-compact lead frame chip-scale packages (LFCSPs). Internally the devices contain four single-pole, single-throw switches with an integrated drive chip providing single-pole, four-throw functionality. Key for automated test applications, both switches are rated for a minimum of one billion actuations.

ADGM1304

Rated for a maximum RF power of 36 dBm, the ADGM1304 has a high-frequency cutoff (–3dB point) of 11 GHz (typical) for RF Channels 1 and 4, and 14 GHz for RF Channels 2 and 3. Insertion loss is 0.26 dB (typical) at 2.5 GHz, while isolation is 24 dB (typical) at the same frequency. Typical on-resistance is 1.6 Ω. Operating on a 3.1 V to 3.3 V supply voltage, the ADGM1304 draws a maximum 3.2 mA. It is supplied in a 24-lead, 5 mm × 4 mm × 0.95 mm LFCSP package.

ADGM1004

With a maximum RF power rating of 36 dBm, the ADGM1004 has a high-frequency cutoff of 10.8 GHz (typical) for RF Channels 1 and 4, and 13 GHz for RF Channels 2 and 3. Insertion loss is 0.45 dB (typical) at 2.5 GHz, and 0.63 dB (typical) at 6 GHz. Isolation is 24 dB (typical) at 2.5 GHz, and 19 dB (typical) at 6 GHz. Typical on-resistance is 1.8 Ω. The ADGM1004 operates on a 3.3 V nominal supply voltage, drawing a maximum of 4 mA. The switch is supplied in a 24-lead, 5 mm × 4 mm × 1.45 mm LFCSP package.

Availability and Pricing

Samples and production quantities of the ADGM1304 are currently available, priced at $36.58 each, in 1,000-piece quantities. Samples of the ADGM1004 are available now, with production quantities scheduled for February 2017. The ADGM1004 is priced at $39.34 each, in 1,000-piece quantities.
