If this connector is on your BOM, the next step is to identify a pin-compatible SMA receptacle from the same manufacturer or a cross-reference from Amphenol, Johnson, or other SMA suppliers. The 50 Ohm interface, flange mount, and microstrip solder termination are the dimensions that need matching. ## RF Performance and Termination Rated for 50 Ohms nominal impedance and a maximum frequency of 18 GHz, this SMA receptacle covers the full L-band through Ku-band spectrum — suitable for microwave test equipment, antenna feeds, and telecom backhaul radios. The contact termination is solder, microstrip, meaning the center pin solders directly to a microstrip trace on the PCB or substrate, while the shield terminates via solder to the flange or ground plane. The 500 mating cycle rating tells you the gold-on-beryllium-copper contact will hold up to repeated connect-disconnect in test or field-service scenarios without the resistance drift you see with tin plating. ## Mounting and Mechanical Details Panel mount with a flange — the four-hole pattern bolts to a chassis or bulkhead, and the threaded coupling nut secures the mating SMA plug. The body is stainless steel, silver in color, with extended insulation around the center conductor for additional creepage and voltage standoff. The 335 V rating covers DC bias injection or RF with a DC component. The PTFE dielectric gives consistent phase response across temperature, which matters when the connector sits outdoors or in an unheated enclosure. ## Sourcing This Obsolete Part Because the 1052528-1 is obsolete, standard distributor stock is depleted. We source it through our broker and surplus network against a firm RFQ. If you need a drop-in replacement, we can research compatible SMA receptacles with the same flange footprint, 50 Ohm impedance, and microstrip termination — just send the BOM line and quantity. No stock-holding claim here; the supply picture is confirmed per inquiry.","metaTitle":"1052528-1 SMA Receptacle, 50 Ohm, 18 GHz, Obsolete","metaDescription":"1052528-1 SMA female receptacle, 50 Ohm, 18 GHz, 500 mating cycles, panel mount.
