April 17, 2017

PMI Model No. 11DP-11R5/16R5-CD-SFF-1 is a diplexer that offers passbands at 10.75 to 12.25 GHz and 15.75 to 17.25 GHz.  The passband insertion loss is less than 3dB and the VSWR is 1.5:1 maximum.  Filter channel 1 has a passband of 10.75 to 12.25 GHz and offers -50 dBc of rejection at 10.25 GHz and -75 dBc of rejection at 13.75 GHz.  Filter channel 2 has a passband of 15.75 to 17.25 GHz and offers -50 dBc of rejection at 17.75 GHz and -75 dBc of rejection at 14.25 GHz. 

Insertion loss flatness of +/-0.3 dB Max. across the passband is achieved with fine tuning and silver plated metal.  The housing measures 3.5" x 1.4" x 0.5" and is offered with field removable SMA female connectors.
