Description
Pasternack’s PE3C5491 50 ohm MCX plug to 75 ohm BNC male cable using 75 ohm RG187 coax is part of our full line of RF
components available for same-day shipping. Pasternack’s flexible RF cable assemblies are ideal for applications where tight
bends and flexure are required. This Pasternack MCX to BNC cable assembly has a plug to male gender configuration with
75 ohm flexible RG187 coax. The PE3C5491 MCX plug to BNC male cable assembly operates to 1 GHz.
Custom versions of most RF cable assemblies can be built and shipped same day. Custom cable assembly lengths can
be obtained by specifying the desired length on the web site at time of order or by contacting a sales representative. Other
available RF cable assembly value added services include connector orientation or clocking, heat shrink booting and custom
labeling. RF testing can also be performed to document the electrical performance of your cable assembly.
