VHF transistors NOW!
NEW `GROWN -DIFFUSED'
TYPES COMMERCIALLY
AVAILABLE IN
PRODUCTION QUANTITIES
HICH CAIN VHF TRANSISTORS with usable power levels and band
widths are now immediately available from Texas Instruments ...
another first for the leading producer of silicon and germanium
transistors. Your design horizons are now extended to include
all- transistor TV, FM, and VHF receivers ... and transistorized
amplifier, oscillator, or switching applications in communications.
telemetering, or radar.
NEW VHF GERMANIUM TRANSISTOR
OSCILLATING FREQUENCY IS ABOVE 250 MEGACYCLES ... alpha cutoff
frequency is 200 mc. Typical gain is 12 db at 100 mc (unregenerative).
This performance in a production transistor was unheard of prior to
perfection of the "grown- diffused" method - an exclusive Texas Instruments
technique.

NEW HF SILICON TRANSISTORS
FREQUENCIES TO 30 MEGACYCLES, rated 30 volts and 125° C, make
these "grown- diffused" units ideal for high temperature military and
commercial applications. They increase to 10 the types of silicon transistors
now available from Texas Instruments, and represent the continual
improvement in frequency, gain, and power made by the pioneer
producer of silicon transistors.
