High power 6 Channel SPST digital micro-switch
New from Menlo Micro is a high-power 6-channel SPST micro-mechanical switch that has been designed to deliver more than 3 billion switching cycles at elevated +85degC temperatures for RF, microwave and DC applications in the defence, aerospace, scientific, medical, industrial and telecoms sectors.
The MM3100 has an operating frequency range from DC to greater than 3GHz, with each of its six switches capable of handling up to 25W RF power (CW) at 3GHz. The device features DC ratings of +/-150V and 1A for each switch with on resistance <0.75 ohm. Channels can be combined to increase DC ratings. On/off switching time is less than 10 microseconds, channel-to-channel isolation is specified as 25dB at 3GHz, and an ultra-low on-state insertion loss of typically 0.3dB at 3GHz helps to enhance overall system performance and maintain high data rates. The switches are individually controlled by a standard Serial Peripheral Interface (SPI) synchronous bus, while an external +5VDC logic supply and +77VDC bias source are required for operation of the internal switch driver. The MM3100 is highly configurable, which allows it to be used in a wide variety of different application circuits, including tunable resonators and filters, impedance matching for broadband power amplifiers, electronically steerable antennas and phase shifters, and automated test and measurement systems. Fabricated using Menlo Micro’s proprietary metal-on-glass DMS (Digital-Micro-Switch) process technology, this robust device is housed in a hermetic 6.0 x 6.0 x 1.3mm BGA package and has an operating temperature range of -40 to +85degC.
