Frequently Asked Questions

Q:What frequency performance can I expect from this adapter?

A:The standard version supports DC to 18GHz with specified electrical performance. The VSWR formula ≤1.05+0.012F(GHz) provides predictable performance scaling across the operating range.

Q:Are the SMA and SSMA thread patterns compatible?

A:No, these interfaces feature different thread specifications (SMA uses 1/4-36 UNS while SSMA uses 10-36 UNS). Direct mating will damage the threads, making this dedicated adapter necessary for proper interconnection.

Q:What is the recommended installation torque?

A:While standard SMA connections typically require 7-10 in-lbs, the smaller SSMA interface demands reduced torque of approximately 4-5 in-lbs. This prevents mechanical over-stress of the coupling mechanism.

Q:How does this adapter affect signal phase?

A:Like all RF interconnects, the adapter introduces a small phase delay based on its physical length. For phase-matched systems, use adapters from the same production lot and verify performance with network analyzer measurements.

Q:Can this adapter withstand extreme temperatures?

A:Yes, the -65℃ to +125℃ operating range covers most aerospace and industrial applications. The PTFE dielectric and gold-plated contacts maintain stable electrical properties across this temperature span.

Q:What testing does each adapter receive?

A:Production units undergo dielectric withstanding voltage testing at 750V and insulation resistance verification exceeding 5,000MΩ. Batch-level testing includes plating quality assessment and RoHS compliance verification.
