Frequently Asked Questions
What characteristic impedance does the GRF1-P-P-08-E-ST-TH1 support, and why is that important for RF designs?
The GRF1-P-P-08-E-ST-TH1 is rated for 50 Ω characteristic impedance, the industry standard for RF transmission lines. Maintaining 50 Ω throughout the connector prevents impedance mismatches that cause signal reflections, insertion loss, and VSWR degradation in systems operating from DC up through several gigahertz, making it critical for antenna, radar, and wireless infrastructure designs.
How does the contact plating of the GRF1-P-P-08-E-ST-TH1 affect its long-term performance?
The GRF1-P-P-08-E-ST-TH1 uses gold (50 µin) plated over nickel (50 µin) on the mating contacts. Gold plating provides contact resistance below 10 mΩ and resists oxidation and corrosion across thousands of mating cycles, while the nickel underplate acts as a diffusion barrier. This combination ensures stable RF performance in humidity-rich or mildly corrosive industrial environments.
Which mounting and body dimensions should PCB designers know when laying out the GRF1-P-P-08-E-ST-TH1?
The GRF1-P-P-08-E-ST-TH1 has a through-hole mounting style with a body length of 1.576 inches (40.03 mm), body breadth of 0.197 inches (5.0 mm), and body depth of 0.177 inches (4.5 mm). Designers should allocate adequate board clearance for the 8 through-hole pins and verify hole diameter tolerance per SAMTEC's recommended footprint to ensure proper mechanical retention and impedance continuity.
In what multi-channel RF system scenarios does an 8-position connector like the GRF1-P-P-08-E-ST-TH1 offer advantages over using discrete single-port RF connectors?
Using a single 8-position RF connector reduces board real estate by consolidating 8 separate RF signal paths into one 1.576-inch body, cutting connector count from 8 units to 1. This approach lowers assembly cost, reduces the number of individual 50 Ω impedance junctions that must be managed, and simplifies cable harness routing in multi-channel antenna systems, software-defined radio platforms, and phased array radar modules.
