Germanium Coaxial Transistor
TI number: G00089

This item is an example of the first caoxial microwave transistor and, possibly, the first germanium microwave transistor, developed in 1962. The type number was TIX3000.

This item was part of the original S/B Lobby Display. The device was developed for Naval Ordnance, China Lake. It produced six decibel gain at 3gHz. Although a high noise factor prevented production, the device pointed the way for further developments leading to the all silicon MERA program.
