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: L-3 - Model: 4946 - Condition: Used and in Excellent Condition - Price: $450.00 USD - Availability: In stock, 4 available - 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 > Isolators (primary) ## Details ### Configuration - Frequency: 8-18 GHz - Isolation (dB Min.): 16 - Insertion Loss (dB Max.): 0.6 - VSWR (Max.): 1.45 - Peak Power, Fwd/Rev (Watts): 15 - Average Power (Watts)  - Forward: 5  - Reverse: 1 - Temperature Range (°C): -20 to +65 ## Function Waveguide ferrite isolator operating from 8-18 GHz with 16 dB minimum isolation and 0.6 dB maximum insertion loss. Provides unidirectional signal flow protection for sensitive RF components by allowing signals to pass in the forward direction while attenuating reverse signals. Handles 15W peak power, with 5W forward and 1W reverse average power capacity. Operates from -20°C to +65°C with maximum VSWR of 1.45. ## Platform Ferrite isolator operates from 8 to 18 GHz with minimum 16 dB isolation, maximum insertion loss of 0.6 dB, and maximum VSWR of 1.45:1. It supports peak forward and reverse power of 15 W, average forward power of 5 W, and average reverse power of 1 W. The device is housed in a module with SMA female connectors and designed for environmental operation between -20°C to +65°C. Typical applications include RF/IF gain control, wireless communications, automated test equipment, microwave radios, and broadband radio systems. ## Application The isolator provides unidirectional signal transmission, minimizing reflected power. It operates within an 8-18 GHz frequency range, achieving a minimum of 16 dB isolation and 0.6 dB maximum insertion loss, with a VSWR of 1.45. The device handles 15W peak forward/reverse power, 5W average forward power, and 1W average reverse power, functioning within a -20 to +65°C temperature range. It interfaces with systems via coaxial connectors, commonly SMA. ## Images - - - -
