Directional coupler for space applications covers 1.0 to 40.0 GHz

November 01, 2017 // By Jean-Pierre Joosting
KRYTAR, Inc., has announce d a directional coupler specifically designed for space applications operating over the ultra-broadband frequency range of 1.0 to 40.0 GHz.

The coupler is uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required.

The latest directional coupler, Model 101040010SQ, adds to the company’s growing family of space-qualified directional couplers by offering superior performance over the frequency range from 1.0 to 40.0 GHz. Technological advances ensure excellent operating performance of this latest stripline design unit. Model 101040010SQ offers superior performance ratings including nominal coupling (with respect to output) of 10 dB, ±1.0 dB, and frequency sensitivity of ±1.52 dB. The directional coupler exhibits insertion loss (including coupled power) of less than 1.3 dB (1-20 GHz) and 1.7 dB (20-40 GHz).

Other features include directivity of greater than 14 dB (1-20 GHz) and 10 dB (20-40 GHz), maximum VSWR (any port) of 1.5 (1- 20 GHz) and 1.7 (20-40 GHz), and input power rating of 20 W average and 3 kW peak. The directional coupler comes with industry-standard 2.4-mm female connectors. The compact package measures just 5.08- x 1.02- x 1.65-mm (LxWxH) or 2.00- x 0.40- x 0.65-inches and weighs only 36.9 grams (1.3 ounces).

These unique couplers undergo additional reliability and quality assurance inspections during all phases of assembly and electrical evaluation. The company's successful space-application heritage offers distinct qualities including: innovative products; quick-reaction capability; design responsiveness; flexibility; fast production turn-around; and close partnerships with customers.

KRYTAR offers complete engineering services for custom designs that meet or exceed critical performance and/or packaging specifications.
