The TT9 SMT series is a new DC – 20GHz wideband surface-mount fixed attenuator Series from Smiths Interconnect optimised to provide performance and power to applications in the defence market. Utilising more than 40 years of experience in refining attenuation solutions for defence, the TT9 offers a power handling capability of 500W while maintaining excellent impedance matching in an SMT package.

The attentuator offers outstanding performance for high frequency applications, both fixed and temperature variable designs in the same footprint and is ideal for the exacting needs of the defence market, specifically for radar, communication and electronic warfare applications.

Significant qualification testing has been undertaken with proven results of robust performance in extended durations and extreme environments. In addition, the RF performance of the attenuator has been characterised on Smiths Interconnect test fixtures with evaluation boards and s-parameters available upon request for ease of design.

These devices have been noted for their excellent performance and small size, measuring only 0.070in. X 0.060in. (1.78 mm X 1.62mm). The TT9 wideband fixed attenuator handles 500mW of input power and is available in dB values from 0 to 10dB in 1dB increments.

The same footprint is also offered in a temperature variable version, the WTVASMTF series, for ultimate design flexibility.

This product is available in a RoHS compliant solder finish and can be supplied on tape and reel for high volume pick and place applications.

In addition, Smiths Interconnect provides custom variations for the frequency band of specific applications on request for defence, aerospace and telecom markets.
