Circulator Test Fixture: Fixture for High-Frequency RF Circulator Performance Testing
Used for high-precision and high-reliability electrical performance testing of RF circulators, supporting the detection of key indicators such as insertion loss, isolation, and VSWR of wideband circulators, and adapting to the packaging form of miniaturized circulators.
Product Preview
Product Highlights
-
Wideband High RF Performance
Covers common RF frequency bands (e.g., 1-40GHz optional), with test link insertion loss ≤2dB and Voltage Standing Wave Ratio (VSWR) ≤1.25, ensuring the accuracy and reference value of test results.
-
Precise Adaptation to Miniaturized Circulators
Custom-designed for the package size of micro/miniaturized circulators, with fixture positioning accuracy ≤0.02mm, ensuring precise contact between circulator pins and test contacts without poor contact issues.
-
High Test Repeatability and Stability
Adopts wear-resistant gold-plated contacts and high-rigidity mechanical structure, with single test deviation ≤0.05dB and repeated test consistency ≤0.1dB, meeting the precision requirements of batch testing.

Advantages
The circulator test fixture is deeply optimized for RF circulator testing scenarios, with core advantages as follows:
High-precision Mechanical Structure Design
The fixture is processed by CNC precision machining with a positioning reference error ≤0.01mm. The circulator has no offset or shaking after placement, ensuring stable contact of RF contacts and avoiding test errors caused by mechanical deviations.
The flip-type pressing structure design is easy to operate with uniform pressing force, which not only ensures contact reliability but also avoids damage to the package of miniaturized circulators.
Low Loss RF Link Design
The RF transmission path adopts high-frequency low-loss laminates and gold-plated transmission lines, minimizing the impact of the fixture itself on test results, and the test data can directly reflect the real performance of the circulator.
The three-port independent RF channel design perfectly matches the port characteristics of the circulator, supporting synchronous testing of forward/reverse loss and isolation, improving test efficiency.
Typical Application Scenarios
- Factory performance testing and batch screening of circulators/isolators in communication base stations and RF modules.
- Performance verification and parameter debugging of high-frequency circulators in radar and satellite communication equipment during the R&D phase.
- Incoming inspection, process testing and finished product acceptance of circulators on RF device production lines.
