coaxial waveguide adapters type n adapters 75 ohm ­ phase matched 8882 series description the 8882 type n 75 ohm adapters are manufactured with a precision version of the maury type n interface to help prevent the inadvertent mating of these 75 ohm adapters to 50 ohm type n connectors a black band is incised into these adapters on the male coupling nut or just behind the female coupling threads 75 ohm n center conductors are smaller than 50 ohm versions so mating a 50 ohm male to a 75 ohm female will destroy the female contact mating a 75 ohm male to a 50 ohm female will result in a poor electrical connection these adapters are phase matched having the same electrical insertion length within their series so they may be readily interchanged in network analyzer measurement applications and for accurate measurement of non-insertable devices 8882e1 8882e2 8882g12 8882g22 interface dimensions contact pin location connector description maury type n 75 ohm connectors are a precision version of the maury type n interface which meets all applicable requirements of iec169-16 they exhibit extremely low vswr and although rated to 2.0 ghz they can be used at much higher frequencies the male connectors are provided with a 3/4-inch hex coupling nut so they can be properly torqued to 12 in lbs see maury data sheet 5e-054 for interface dimensions specifications frequency range dc ­ 2.0 ghz maximum vswr 8882a/b/c 1.03 all 75 ohm to 50 ohm models 1.5 75/50 ohm typical calibrated out during the measurement calibration process nominal impedance 75 ohm available models between-series model 8882e1 adapts side a side b nmd3.5mm f 50 2 type n f 75 1 insertion length inches cm 1.003 1.603 1.748 1.748 1.748 1.748 2.277 2.277 2.634 2.634 2.634 2.634 2.5476 4.0716 4.4399 4.4399 4.4399 4.4399 5.7836 5.7836 6.6904 6.6904 6.6904 6.6904 8882e2 nmd3.5mm f 50 2 type n m 75 1 3.5mm f 50 3 8882g11 type n f 75 1 8882g12 type n f 75 1 8882g21 type n m 75 1 3.5mm m 50 3 3.5mm f 50 3 3.5mm m 50 3 7mm 50 4 7mm 50 4 type n f 50 5 type n m 50 5 type n f 50 5 type n m 50 5 available models in-series model adapts side a side b type n f 75 1 type n m 75 1 type n m 75 1 insertion length inches cm 2.768 2.768 2.768 7.0307 7.0307 7.0307 8882g22 type n m 75 1 8882d1 type n f 75 1 8882d2 type n m 75 1 8882f11 type n f 75 1 8882f12 type n f 75 1 8882f21 type n m 75 1 8882f22 type n m 75 1 8882a type n f 75 1 8882b type n m 75 1 8882c type n f 75 1 1 precision type n 75 ohm per maury data sheet 5e-054 2 nmd3.5mm per maury data sheet 5e-084 3 precision 3.5mm per maury data sheet 5e-062 4 precision 7mm per maury data sheet 5e-060 5 precision type n per maury data sheet 5e-049 key literature maury data sheet 2b-031 maury microwave corporation 117 vna calibration kits microwave components adapters
