Sinclair Technologies, a division of Norsat International, and a leading provider of customizable land mobile radio communication solutions, has announced the launch of the Intellitune series of auto-tunable combiners that are completely automated in detecting and tuning transmitter frequencies in the field dynamically to enable flexible wireless applications.

The new Intellitune series of auto-tunable combiners 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, according to the  company. 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 to 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 multiples of 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. The 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

“Sinclair is pleased to introduce the Intellitune series, the world’s leading smart transmitter combiners with cutting-edge technology and optimized architecture. The unique aspect of this 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 key, or for systems that often require changes to their operating frequencies” said Wee Er, general manager of Sinclair.
