Sinclair Introduces Auto-Tunable Combiners for the UHF Band

Leading provider of land mobile-radio communication solutions, Sinclair Technologies, has unveiled a new Series of Auto-Tunable Combiners called INTELLITUNE. These combiners can automatically detect and tune transmitter frequencies in the field dynamically to enable flexible wireless applications. The series features an integrated control unit for fully autonomous frequency tuning to keep return loss to a minimum and constantly optimize overall performance.

The Auto-Tunable Combiner is designed with a high unloaded quality factor, wide tuning range, high linearity, high power handling, low weight, compact dimension, and outstanding reliability. The user-friendly web-based graphical user interface (GUI) facilitates easy on-site configuration and remote access. The first models to be released in this series cover 350-512 MHz in the UHF band and are available in 2-channel or 4-channel base configurations. They are easily expandable to up to 32 channels by adding multiple 2-channel slave units. Moreover, the compact design of the cavity filters allows the 2-channel module to easily fit into a standard 4U high, 19-inch rack.

Additional features include:

  • Wide tuning range with outstanding tuning accuracy and quick tuning time
  • Wide power handling range from 1 to 100 Watts per channel
  • Tx-Tx spacing down to 150 kHz
  • User-friendly web-based GUI for comprehensive remote alarm monitoring including frequency, power, return loss, as well as transmit power and VSWR of each carrier at the antenna port
  • Secure user administration with role-based access control (RBAC) feature and system audit trails
  • SNMP protocol for integration with Network Management Systems

The INTELLITUNE Series are innovative SMART transmitter combiners with cutting-edge technology and optimized architecture. The unique aspect of the product is that it enables fully autonomous frequency tuning on the fly, which means customers can now deploy this product without knowing precise TX frequencies. This is an ideal product for emergency situations where flexibility and rapid deployment are the key, or for systems that often require changes to their operating frequencies.

Sinclair will be launching (booth #415) the series at the APCO 2019 show to be held in Baltimore, MD from August 11-14. The products are available for pre-order with first shipments scheduled in Q4 2019.
