Impedance matching pads preserve signal integrity by matching virtually any transmission line. Model 851-879-FMB is a 50 Vdc maximum blocking, 50Ω SMA female to 75Ω F male impedance matching pad rated 1-Watt average power. The operating frequency range is 30 – 3000 MHz, insertion loss is 5.7 dB nominal, and VSWR is 1.50:1 maximum. Impedance matching pads eliminate impedance discontinuity (mismatches) without introducing reflection to the circuit. We currently manufacture over 160 standard impedance matching pads in different connector combinations, frequency ranges and impedances.
