SI-9150 Polaris VHF/UHF Multichannel Wideband Tuner

1 to 5 Channels, 2 MHz – 6.2 GHz Frequency Range, 40 or 85 MHz Bandwidth Tuner

The Polaris tuner family builds on a 50-year legacy of continuous innovation in the design of state-of-theart HF/VHF/UHF tuners and receivers. Polaris’ high performance and small form factor set it apart from other RF front ends in the industry. Polaris’ low cost per channel and powerful features open the door for its use in a range of military and commercial applications. 

With a frequency coverage of 2 MHz to 6.2 GHz, Polaris can intercept a wide range of signals of interest and provide a wide bandpass from each of its channels. Polaris is available as an analog or digital tuner with up to four channels. The Polaris digital tuner is also available as a five-channel unit. Each of its wideband channels can operate independently or phase-coherently providing a unique ability to tailor this sensor to a wide range of missions. 

Polaris tuners are well-suited for commercial applications such as identification and geo-location of RF interference. Polaris possesses capabilities that are both critical to the development of emerging commercial cognitive radio networks and paramount to spectrum monitoring, signals intelligence, direction finding and beam forming applications.

Weighing no more than 4.3 pounds and as little as 0.5 pounds, Polaris easily fits in the palm of your hand. Polaris tuners are easily the smallest in their class of signal intelligence collection tuners. They consume little power, and their rugged mechanical design allow optimal performance in harsh environments and over a wide temperature range.

Why Polaris?

• Smallest Tuner for SIGINT Collection 
  Weighing less than four pounds and consuming little power, Polaris fits in the palm of a hand with average dimensions of three inches wide and five inches in length.
• Rugged Radio Optimized for a Wide-Range of Environments
  Polaris’ small size, weight and power make it ideal for platforms including vehicle, airborne (up to 50,000 feet), marine and antenna integration. Polaris is tested in real-life and lab-setting signal environments.
• Best in Class Performance
  Polaris’ excellent intermodulation and phase noise performance enables the extraction of weak signals from dense signal environments, such as urban areas and in the presence of strong signals.

Commercial & Military Applications

As a front-end tuner to a system, Polaris can optimize the wireless spectrum to its fullest potential and adaptively juggle a wide range of signals with minimal interference.
