A marriage of two proven technologies,
the IOT and the multiple stage depressed collector,
the Constant Efficiency Amplifier (CEA) is the most
efficient UHF TV amplifier available. Designed for
DTV,
the L-3 CEA 130 reduces transmission costs by over
$20,000 per tube per year. Excellent linearity allows
full correction
across the entire UHF band while delivering 30 kW
of average power (130 kw peak power) in 8VSB service.
PAO
synthetic oil cools and electrically insulates the
MSDC collector, saving thousands of dollars in maintenance
and repair costs over the life of the transmitter.

The L-3 IOT 80T and L-3 IOTD
130T are high efficiency tube and
circuit assemblies capable of operating in the UHF-TV
frequency range of 470-810 MHz. The amplifiers are designed
for new analog and digital transmitters requiring combined
vision/aural service, vision-only service as well as aural-only
service. When equipped with a L-3 IOT 80 or L-3
IOTD 130, the units are capable of 30 kW average/130
kW peak output in 8VSB digital service or 70+7 KW in common
mode service.

The L-3 IOT 60/L-3 IOTD 110 is designed
for the most widely used applications in today's IOT transmitters.
Designed as a drop in replacement for the Marconi 7360/8404/8600
IOT's, the L-3 IOT 60/L-3 IOTD 110 will provide
outstanding performance in a wide variety of transmitters
and unique operating conditions. Covering the complete
range of UHF operating frequencies with 22 dB gain and
44+4.4 kW output, the L-3 IOT 60/L-3 IOTD 110 is
the broadcaster's choice for replacement tube performance.

The L-3 IOT 80/L-3 IOTD 130 is
the highest power IOT in the L-3 Electron Devices inventory.
With the advent of digital television, the L-3 IOT
80/L-3 IOTD 130 offers the broadcaster the ability
to operate at 130 KW peak power for greater viewing
area coverage. Yet the tube can still fit in a standard
size circuit assembly and typical OEM transmitter cabinet.
For analog use, the L-3 IOT 80 is a 70+7 KW tube,
matching the newer needs of many TV stations.

L-3 Communications Electron Devices
manufactures the L-4945A thyratron for installation
in broadcast transmitters. Designed to be equivalent
to the E2V CX 2708, the L-4945A offers broadcasters
a reliable and economic alternative for performing
crowbar
operations in IOT transmitters.
Electron Devices has been synonymous
with the design and production of microwave devices
- magnetrons, klystrons, traveling wave tubes for military
and commercial customers worldwide. But it has also
developed a fine reputation for producing an extensive
line of ceramic/metal thyratrons. Customers from the
laser and scientific markets as well as the medical
and industrial sectors have been using L-3 Electron
Device thyratrons for over 15 years. These devices are
produced using rigorous military standards such as Mil-I
45208 and MIL-Q-9858A assuring unequaled reliability
and long lasting performance.
