WISCO International (CELWAVE TJD140 Series)

Each of these RFS cavity-ferrite combiners utilizes a precisely tuned copper cavity junctioned with our single, dual or triple isolator. They are designed to couple several transmitters into one antenna.

The TJ Series is available in either 2, 3, 4 or 5 channel units or in multiples of up to 20 channels. Minimum channel spacing is 120 KHz.

The TJ Series is designed for maximum Q, excellent heat transfer and the lowest possible insertion loss. Each unit is factory tuned and mounted on a standard 19 inch rack panel.

Features/Benefits

� Allows combining of two or more transmitters
Maximizes use of tower space, reduces costs.

� High isolation
Minimizes intermodulation.

� Modular
Simplifies on-site expandability.

� Fully temperature compensated
Ensures consistent performance across temperature and power range.

� Field Expansion
To combine multiple cavities requires additional modules and frequency dependent cable harness. Both new and old frequencies must be specified.
