These switch modules use RF relays in a stubless tree switch configuration to provide 75 ohm impedance modules.
CXR/2×2-G Modules Often referred to as Transfer or baseball switches. They have a Normally Closed (NC = A-B, C-D = OFF) and Normally Open (NO = A-C, B-D = ON) Position. 75 ohm Bandpass of DC to 1.2 GHz. Isolation of -60 dB to 800 MHz. VSWR = 1.25:1 @ 1 GHz Switched Power = 10 Watts BNC or SMB 75 ohm connectors.
