Toshiba claims to have developed of the world's smallest and lowest noise radio frequency transistors for low noise amplifier applications.

Toshiba claims to have developed of the world's smallest and lowest noise radio frequency transistors for low noise amplifier (LNA) applications.

Based on the company's advanced silicon germanium (SiGe) technology, Toshiba's new MT4S102T and MT4S104T microwave transistors are ideal for LNA designs in applications such as wireless LANs and global positioning systems (GPS).

The MT4S102T has a noise figure of just 0.58dB and is targeted at 2GHz band applications, whereas the MT4S104T has a noise figure of only 1.25dB and is suited to 5GHz band designs.

Both the new transistors are packaged in Toshiba's 4-pin TESQ package.

This package has dimensions of just 1.2 x 0.9 x 0.52mm, making the parts the world's smallest devices to offer this level of functionality.
