Cobham's Electronic Attack (EA) or Electronic CounterMeasures
(ECM) products and services provide the components, modules, and
subsystems that are used in communications jamming, Integrated Air
Defense Systems (IADS) suppression, Directed Energy Weapon
(DEW)/LASER attack, expendable decoys (chaff and flares ),
and Radio Controlled Improvised Explosive Device (RCIED)
These pod based Solid State and Travelling Wave Tube
transmitters, comprised of amplifier, antenna, power supply,
control and cooling subsystems, are characterised by wide operating
bandwidth, high output power and high reliability.
The EA-18G carries Cobham's integrated antenna/radome and Low
Band Transmitter, designed to protect strike aircraft, ships, and
ground troops by disrupting enemy radar and communications.
Exciters for radar and communications
Exciter expertise encompasses both radar and communications
waveform generation using both analog and digital techniques.
Signal generation via Direct Digital Synthesis allows fast tuning,
programmability and flexible modulation.
High Power Transmit Antennas
Cobham developed very high power antennas for fixed and ground
mobile applications. These antennas have been used in jamming
systems, threat simulators and communication systems.
Developed and delivered the Band 9/10 Transmitter for the EA-6B,
EA-18G and the AN/ALQ-99 Tactical Jamming System. Key to
achieving cost effective long range standoff jamming was
development of technology to allow coherent RF combining of
multiple high power TWT Amplifiers.
