Important Usage Notes

• This K-type millimeter-wave adapter is designed exclusively for DC-40GHz high-frequency microwave testing, not recommended for low-frequency circuits below 1GHz.
• Control screwing torque moderately during installation; excessive tightening force will deform inner gold-plated pin and damage original electrical parameters.
• Store in dry, dustproof environment to protect precision gold plating against moisture corrosion.

FAQ

Q1: Can this 2.92mm adapter mate directly with standard SMA connectors?

A: Yes, the K-type(2.92mm) features identical mechanical thread size with SMA, supports direct plug-in interconnection with all regular SMA male/female connectors for hybrid test setup。

Q2: Does it maintain stable VSWR performance under full DC-40GHz continuous operation?

A: Yes, factory precision machining ensures VSWR ≤1.25 across the entire DC~40GHz working frequency range with low insertion loss.

Q3: Are bulk discount available for lab/enterprise bulk purchase?

A: Volume discount is available for orders over 50 pieces, contact our sales team to get customized wholesale quotation.

Q4: What’s the advantage of SU303 passivated stainless steel housing?

A: Passivation process removes free iron on stainless steel surface to avoid secondary oxidation and rust, stable performance under wide -55~+165℃ temperature fluctuation, greatly extend service life in harsh industrial & lab environment。
