INTRODUCTION

CSI16T is a passive wideband combiner designed to work up to 3W of power.

CSI16T communicates with Wisycom transmitter (i.e. MTK952N) through coaxial inputs and
allows a smart power management: combiner loss are automatically compensate on Tx side!

FEATURES

 Selectable combination thru a 3 positions selector on front panel

[16:1] or 2x [8:1] or 4x [4:1]

 Used with MTK952N permits to recover the combiner loss
 Wide band operation 470÷800MHz
 High input power up to 3W
 Selectable extra compensation in the [16:1] configuration: connected to

another combiner CSA121T, it is able to recover up to 15dB of loss
