The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: RLC Electronics - Model: SM-2 MIN - Condition: Used and in Excellent Condition - Price: Quote only - Availability: Not in Stock - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 1 lb, estimated - Shipping dimensions: 8X8X3 in, estimated ## Categories - Test Equipment > Electrical Test > Switches (primary) ## Details ### Configuration - Manual - Outboard Mounting - Frequency Range: DC-18 GHz ## Overview Miniature single-pole, double-throw (SPDT) coaxial switch designed for high-reliability RF signal routing with frequency coverage from DC up to 18 GHz nominally, with options extending to 26.5 GHz, 40 GHz, 50 GHz, or 65 GHz. Features low insertion loss (as low as 0.1 dB at DC-4 GHz), low VSWR (typically 1.2:1 to 1.9:1 depending on frequency), high isolation (minimum 50 dB to 80 dB depending on frequency band), and operates at 50 ohms impedance. Compact miniature housing less than 0.75 cubic inches using high-density packaging technology. Interfaces via SMA connectors and can be controlled manually or remotely, designed for integration in high-frequency test and measurement or communication systems. ## Function Provides single-pole, double-throw (SPDT) switching for coaxial transmission lines with very low insertion loss, high isolation, and low VSWR over a broad frequency range up to 65 GHz, enabling reliable signal path selection in RF test and measurement, communication systems, and microwave applications. Supports high-density packaging in compact form factors suitable for integration in complex RF circuits requiring fast, precise switching of microwave signals with 50-ohm impedance compatibility. Designed for manual or remote control operation in precision RF environments. ## Platform A miniature, single-pole, two-position (SP2T) failsafe coaxial switch designed for high-reliability RF and microwave applications. It interfaces via SMA female connectors for RF signals and solder lug terminals for DC actuation voltage (e.g., 12 VDC, 28 VDC). Its compact design is ideal for integration into automated test equipment (ATE), communication systems, radar, and satellite ground stations where space is critical and signal path integrity from DC to 26.5 GHz must be maintained. ## Application Performs signal routing in radio frequency (RF) and microwave systems where space constraints are critical. Operates in communication systems, test equipment, radar, electronic warfare, and satellite communications up to specified frequency ranges. Supports automated test environments requiring rapid signal path reconfiguration with minimal insertion loss. Used in mobile or compact deployments where standard switches would be impractical. Enables dynamic impedance matching and signal selection in multi-band RF systems. ## Accessories Type N female, SMA female, and TNC female connectors available, requires +28 VDC @ 200 mA power supply for switching, uses TTL positive logic control interface with BNC connector, may need position indicator with LED display, optional switch driver for remote operation, requires mounting hardware, adapter cables for control signals, and RF cable assemblies matched to selected connectors. ## Interface SMA female connectors, 50 ohm impedance, frequency range DC-18 GHz, operating voltage 28 VDC, TTL control logic, D-subminiature connector for control signals (9 pins). ## Images - - - -
