A 50Ω 4 to 1 PXI RF MUX available with 1, 2 or 4 banks in a single PXI slot. All versions exhibit low insertion loss and VSWR through the use of modern RF relay technology at an affordable cost. Each MUX has been carefully designed to ensure excellent and repeatable RF characteristics to frequencies of 3GHz with each path having a nominally equal insertion loss. The injection of noise and unwanted signals into the signal paths of this RF MUX has been minimized by careful attention to the mechanical and electrical design. 

Need a higher density solution but can accept lower performance? Try the 40-755 10 off 4:1 RF MUX.
