Frequency Ceiling and Impedance — Why 12.4 GHz Matters
The 132147-29: The 12.4 GHz max frequency sets the usable bandwidth for this SMA receptacle. At 50 Ohm nominal impedance, it is designed for matched transmission lines up through X-band. If your application runs above 12.4 GHz, the sibling 132134-11 extends to 18 GHz — same 50 Ohm impedance, same gold finish, same 500-cycle mating life, but a jack rather than a receptacle body style.
Mounting and Termination — Panel Fit Checklist
The extended insulation feature adds creepage distance beyond the standard SMA interface, useful when the connector sits near a chassis ground or in a high-voltage bias-T circuit. Mating cycles are rated at 500, typical for gold-plated SMA interfaces; the gold-on-gold contact pair keeps resistance stable over that life.
