It is a same-series barrel adapter that joins two SMP male connectors end-to-end, maintaining a 50 Ohm impedance path through the junction. This adapter is built for free-hanging, in-line use where a rigid RF interconnect needs to bridge two SMP jacks without a bulkhead feedthrough. ## 26.5 GHz Bandwidth and 50 Ohm Impedance The 26.5 GHz maximum frequency covers the full Ku-band and most of the K-band, making this adapter suitable for satellite communications, radar test setups, and microwave instrumentation. The 50 Ohm impedance matches the standard RF system impedance — no impedance transformer needed when inserting this barrel between two 50 Ohm SMP ports. The straight body keeps the signal path short and the insertion loss low; a right-angle adapter would add a reflective discontinuity at these frequencies. ## Snap-On Mating and Free-Hanging Installation Both ends use the SMP snap-on fastening — push to engage, pull to disengage. No threads, no torque wrench. ## Temperature Range and Materials Gold plating on both the body and centre contacts prevents oxidation in humid or corrosive environments.","metaTitle":"SMP-FSBA-145 SMP Barrel Adapter, 50 Ohm, 26.5 GHz","metaDescription":"SMP-FSBA-145 straight SMP plug-to-plug adapter, female-to-female, 50 Ohm impedance, rated to 26.5 GHz.
