FTS0085P: Test Fixture for Microstrip Couplers
Designed for R&D verification, parameter testing and production screening of general-purpose microstrip coupler operating at 6GHz frequency band, providing stable, reliable and highly repeatable test interfaces.
Core Product Highlights
-
Seamless SMA Coaxial Adaptation
Seamlessly converts the microstrip planar interface of the bridge to standard SMA coaxial ports, facilitating connection to test equipment such as vector network analyzers. Features short signal path and excellent impedance matching to ensure signal integrity within the 6GHz frequency band.
-
High Isolation and Phase Balance Assurance
The fixture structure is optimized through electromagnetic simulation to minimize signal crosstalk and parasitic effects. Ensures minimal error introduced by the fixture itself when measuring key isolation (≥18dB) and phase balance (±5°) indicators of the bridge, delivering true and reliable measurement results.
-
Complete DC and RF Interface Support
Supports full-function testing of the bridge's four ports (Input, Isolation, -3dB/0°, -3dB/-90°). Internal design fully considers grounding continuity, meeting the bridge's rated power requirement of up to 100W and ensuring safety during high-power testing.
-
Robust and Wide Temperature Test Support
Matches operating temperature range of -55℃ ~ +85℃ and storage temperature range of -55℃ ~ +100℃. The fixture maintains stable performance in wide temperature environments, suitable for high and low temperature reliability verification tests.
