SMT SMI2040 3-Port Broadband Connectorized Isolator/Circulator Description
Functions
Enables unidirectional signal transmission, isolates RF components from reflected power, and provides three-port signal routing within a broadband frequency range using SMA connectors.
Platforms
This RF component functions as a non-reciprocal ferrite device, directing broadband electromagnetic waves sequentially between three ports or isolating one port from reflections. It's engineered for integration within RF/microwave communication systems, radar front-ends, and test instrumentation platforms. Connecting via standard RF coaxial connectors, it interfaces with antennas, power amplifiers, mixers, and transceivers. Primary applications include VSWR protection, duplexing for shared antenna TX/RX paths, signal routing, and ensuring system stability in high-frequency transceiver architectures.
Applications
Used in RF/microwave systems for non-reciprocal signal routing, protecting active components like power amplifiers and oscillators from damaging reflected power, and improving system stability. Facilitates duplexing in antenna systems and serves as a critical element for enhancing impedance matching and reducing intermodulation distortion in broadband communication links and radar front-ends. Essential for isolation in measurement setups.
Accessories
Requires SMA connectors for RF ports, typically 3 connectors (one input, two output ports), mounted with female SMA connectors 50 ohm, frequency range 0.5 to 4.0 GHz; requires precise RF test equipment or integration into broadband RF systems; may need torque wrenches for SMA connector installation; no additional mainframe or chassis needed.
Interfaces
RF input port (SMA female), RF output port (SMA female), isolated port (SMA female); 2.0 to 4.0 GHz frequency range; 20 dB minimum isolation; 0.5 dB maximum insertion loss; 1.25:1 maximum VSWR; handles up to 10W average RF power; threaded SMA connectors with gold-plated center pins; compatible with 50O impedance systems; requires no external bias or control signals; passive device needing no power source.
Specifications
A passive, 3-port, connectorized ferrite device configurable as an isolator or circulator for the 2.0-4.0 GHz frequency range. It provides high isolation to protect source components from reflected signals and low insertion loss for signal integrity. Interfacing via three SMA female coaxial connectors, it is integrated into RF/microwave systems. Common applications include amplifier protection, duplexing in transceivers, and signal routing in test benches, radar, and electronic warfare (EW) systems.

What Customers Are Saying
- Dylan S. Google
Great customer service. good prices and knowledgeable staff!
- Kamal A.
We found Artisan when our PXI Chassis broke, which shut down our production line. We were up and running in less than a day because they shipped overnight and talked our tech guys through the installation over the phone. ATG saved the day big time!
- Gareth A.
We bought a Parker Compumotor Controller for our press and installed it 2 weeks ago. Easy fix for our machine and it is working perfect.
- Lonnie G.
Don’t worry about damage to your items during shipping – the box ours came in could have taken a beating and would have still survived!
- Tia W.
Quick process from getting a quote to getting the items we ordered.
- Terra N. Google
