new approach to telemetry circuits, particularly in space applications, is suggested by General Electric in a line of small ceramic receiving tubes and "TIMM" ceramic circuits, which offer exceptional high gain and low noise performance at high frequencies. 111 addition, they are extremely tolerant of heat, variations in ambient temperatures, mechanical vibration and shock, and nuclear radiation.
"TIMM" circuits (thermionic integrated micro-modules) are said by General Electric to be ready for development into whatever specific circuitry is needed--and offer such possibilities as the equivalent of a 100-tube computer the size of a package of cigarettes. Ii1 TIMM circuits all necessary components such as resistors, capacitors, and tube elements are stacked, evacuated and sealed to form ceramic capsules which thrive on heat.
They are intended to be thermally insulated and operate principally on the heat generated within themselves --at near 600ยฐC. They thus offer a practical solution to component density requirements equivalent to a million parts in each cubic foot.
Outstanding among ten types of ceramic receiving tubes is a developmental low-noise, broad-band triode amplifier which features transconductance of 40,000 micromohos.
Capable of operating at high temperatures, ceramic receiving tubes deliver the ultimate in high frequency performance in the small tube range without the use of blowers or other bulky, inefficient cooling systems
