The Taiwan based connector and cable assembly manufacturer Frontlynk offers all kinds of RF connectors and adapters up to 110 GHz, for special connecting needs they have an answer ready by 3-6 weeks which is really hard to beat.
They describe themselves as certainly not being the biggest supplier in the world, neither the most famous. They believe this to be a big portion of their strength: the team is either young and energetic either experienced enough to try that little harder and to be that little bit more flexible to match their clients’ needs best possible.
