Amplifier Systems for Ultrasonic Phased Arrays
Electronics
and Innovation's extensive amplifier research has led to the
development of amplifier systems with controlled delay and phase for
each amplifier module for linear or curved arrays of ultrasonic
sensors. These highly linear phased array amplifiers are available
in class A or AB designs with 2 to 61 channels, RF powers up to 100W
per channel and for frequencies from 250kHz to 150MHz. Please call us to get more details
HF and VHF Amplifier Modules
E&I is renowned for its highly inear, robust and reliable HF amplifiers. That technology is now available as modules, pallets and subsystems. They are available in various power classes from 1W to 400W for frequencies from 10kHz to 35MHz, e.g. for ultrasonic applications or ISM band applications at 13.5MHz and 27MHz. Other combinations of power and bandwidth are available upon request.
