10 (1x4) Coaxial Trees - 75 Ohm Tree > 500MHz. The SMP6201 high-density (1x4) coaxial tree and SMP6202 high-density (1x2) coaxial switch modules are designed for general purpose 75 ohm RF switching. The front panel contains two high-density, 26-pin coaxial connectors designed for high reliability and superior signal integrity. These modules are designed for high-density 75 ohm applications under 500 MHz. The SMP6201 and SMP6202 are part of the SMIP II ™ family and can be mixed and matched with other SMIP II ™ modules to configure high-density switching systems.
