Product details

SMP Barrel Adapter for Inline RF Paths

The Amphenol RF SMP-FS2A-990 is a straight SMP-to-SMP adapter — a female-to-female barrel that joins two SMP plug interfaces end-to-end. This adapter is a free-hanging inline component with no panel or PCB mount — it floats in the cable run, so the installer provides strain relief on both sides.

The 26.5 GHz max frequency means the adapter is characterised through the full SMP operating band; above that frequency the barrel geometry starts to resonate and insertion loss climbs. For a 100 mating-cycle life, the gold-plated BeCu centre contacts and snap-on retention are typical of SMP blind-mate interfaces — not a high-wear design, so factor in replacement for test-fixture duty where connectors are mated daily.

Frequently asked questions

Where can I buy SMP-FS2A-990 and how do I get a price?

Submit a request for the quantity you need; current pricing and lead time are confirmed at quote time.

Is SMP-FS2A-990 a female to female adapter?

Yes, the SMP-FS2A-990 is a female-to-female SMP barrel adapter — both ends present an SMP plug with a female socket centre contact, so it joins two male SMP cable ends or PCB-mount jacks.

What is the impedance of SMP-FS2A-990?

The impedance is 50 Ohm nominal, matching the standard RF system impedance for telecom, test, and microwave interconnects.
