E&I provides RF systems for Phased Array applications. We design Phased Array Systems with as few as 2 channels, up to 61 channels. Our Phased Array Systems offer separate channels that can be driven independently by varying the input signal. Dual channels can be employed as modules to provide multiple channels as well as full rack systems.

  • Incorporated gain control of individual channels

8 Channel 90 Watt RF Amplifier System
Description N/A The 75A2 is a broadband solid state amplifier system covering the frequency spectrum from 300 KHz to 35 MHz. Each channel is rated at 75 watts of RF power with low harmonic and intermodulation distortion. Over 125 watts of saturated power can be produced with increased distortion products. A highly linear Class A design, the 75A2 will amplify inputs of AM, FM, SSB, pulse and any complex modulation signals. The amplifier has 50 dB gain it is unconditionally stable and will not oscillate even with combinations of mismatched source and load impedance. It is protected against failure due to output load mismatch and/or overdrive.

 		N/A The E&I 50AB6 is a broadband solid state amplifier system covering the frequency spectrum from 500 KHz to 3 MHz. It is rated at 50 watts of RF power per channel. A quasi linear Class AB design, the 50AB6 will amplify inputs of AM, FM, SSB, pulse and any complex modulation signals. Each channel has 30 dB gain, that is variably controlled by a 0 to 10 Volt signal

         		N/A The 10AB61 produces 10 Watts per channel that is controlled by a DC input of 0 to 10 Volts. The individual channels are phased matched to facilitate operation in phased array systems. The gain control is implemented by the control of the RF MosFet bias through a logrithmic amplifer. Thereby, reducing the phase change with power change.

         		N/A The E&I 90AB8 is a broadband solid state amplifier system covering the frequency spectrum from 250 KHz to 150 MHz. It is rated at 90 watts of RF power per channel. A quasi linear Class AB design, the 90AB8 will amplify inputs of AM, FM, pulse and complex modulation signals. Each channel has 50 dB gain. Each channel has its own dedicated input and output. However, these maybe configured to a single input and single output to provide up to 700 watts
