Tiny surface-mount attenuators work up to 20GHz

Called TT9 SMT, the series is aimed at the defence market and “has undergone significant qualification testing with proven results of robust performance in extended durations and extreme environments”, according to the firm. Operating temperature is -55 to +150°C.

Size is 1.78 x 1.62mm and the devices are available across 0 to 10dB in 1dB increments. Attenuation is ±0.5dB up to 15GHz.

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

RoHS and Sn-Pb versions are available

RF performance has been characterised on Smiths’ test fixtures, with evaluation boards and s-parameters available upon request for ease of design.

Applications in radar, communication and electronic warfare are expected – and custom frequency band variations are available for defence, aerospace and telecoms.
