Product details
The 903-499J-51P by Amphenol RF represents the pinnacle of precision engineering in Coaxial Connectors (RF) technology. Developed for test and measurement applications, this connector delivers laboratory-grade performance in field-deployable packaging with exceptional repeatability.Featuring SMB interface geometry, the connector achieves >60dB return loss up to {Frequency - Max}. The air dielectric design minimizes dispersion for time-domain applications.The Receptacle, Male Pin configuration provides genderless mating capability for flexible system integration. The anti-binding design ensures smooth engagement even in misaligned conditions.With Solder technology, the connector maintains <0.5dB insertion loss variation over 10,000 connect/disconnect cycles. The gas-tight interface prevents oxidation in harsh environments.Solder methodology ensures <0.1nS ground path inductance. The multi-finger contact design provides 360 shielding effectiveness >100dB at 18GHz.The 50Ohm controlled design features stepped impedance matching for broadband performance. Full 3D EM simulation verifies <1% impedance deviation across the operating band.Optimized for Through Hole applications, the connector features integrated anti-rotation tabs. The captive hardware meets NASM 25027 torque specifications.The Snap-On mechanism provides positive engagement with 15-20 in-lbs torque. The self-locking design prevents loosening under vibration per MIL-STD-810G.Characterized up to 4 GHz, the connector exhibits <0.05dB ripple in insertion loss. The precision-machined interface minimizes higher-order mode excitation.With 1 independent RF paths, the connector supports simultaneous multi-band operation. Each channel features <-70dB cross-talk isolation up to 40GHz.Key Board Lock include integrated phase compensation for cable length variations. The connector is calibrated traceable to NIST standards for metrology applications.The Gold housing material provides excellent RF transparency with <0.001 dielectric loss tangent. The UV-stabilized compound resists yellowing over time.The Brass core features proprietary annealing for optimal spring characteristics. Contact resistance remains <5m after 25,000 mating cycles.
