Description
N 50 Ω Jack to F 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-N25F27A-2G/H4-H4 impedance matching pad is engineered to provide stable impedance conversion between N 50 Ω jack (female) and F 75 Ω jack (female) interfaces. Supporting operation from DC to 2 GHz, this model maintains a VSWR of ≤ 1.25 with an insertion loss of ≤ 5.7 dB ± 0.5 dB. Insulation resistance is rated at ≥ 5 GΩ, with a test voltage of 1000 V rms and a working voltage of 335 V rms. RF leakage performance is specified at ≥ 100 dB up to 1 GHz.The MP-N25F27A-2G/H4-H4 utilizes screw-lock coupling mechanisms on both N and F sides, offering secure mechanical engagement and a mating durability of ≥ 500 cycles. Center contacts are manufactured from phosphor bronze with gold plating over non-magnetic nickel-phosphorus underplating. The connector body and coupling nut are constructed from brass with copper–tin–zinc alloy plating, while PTFE insulators and a silicone rubber gasket provide stable electrical and mechanical performance.
ROSNOL impedance matching pads are produced under ISO 9001-certified quality management systems and are fully compliant with RoHS and REACH requirements. Combining reliable RF performance, high-quality construction, and cost-effective pricing, ROSNOL products serve as dependable alternatives to impedance matching solutions from major European and American brands. Customization services are available upon request.
