PSMP-FSBA-1970 — 50 Ohm In-Line Adapter for 10 GHz Signal Paths
The Amphenol PSMP-FSBA-1970 is a straight, in-line adapter that joins two PSMP plug interfaces — female socket to female socket — for extending or rerouting a 50 Ohm RF path. Rated to 10 GHz, it sits at the upper end of the PSMP series frequency range, making it a clean fit for microwave test setups, telecom backhaul modules, and airborne antenna feeds where the signal must stay in the same connector family without an impedance step.
10 GHz Ceiling and 100-Cycle Mating Life
Below that ceiling the insertion loss and VSWR stay within the PSMP interface spec. The 100-cycle mating life is moderate: fine for a test bench adapter or a field-replaceable jumper that gets swapped a few times a year, but not for a production test handler running thousands of cycles. The gold-plated beryllium copper centre contacts resist fretting through those 100 mates, and the snap-on fastening gives a positive tactile lock without requiring a tool.
There is no official cross-reference or direct second-source replacement listed for this exact PSMP-to-PSMP adapter, so the BOM line stays specific to this order code.
