ETRAB4103

RF Antennas

ETRAB4103 is an active electronically scanned array (AESA) transceiver for use in radio frequency (RF) applications. This AESA transceiver is comprised of four radio-frequency modules - three receive modules and one transmit module. The ETRAB4103 provides a wide bandwidth of operation across S-Band, L-Band, and UHF/VHF frequencies. It can be used in applications such as military and commercial aircraft, and military radars.

Application Field

ETRAB4103 is mainly used in the airborne electronic warfare segment for applications that require high-end low-noise performance. It is suitable for use in radio-frequency applications such as airborne electronic countermeasures, radar signals jamming, and communications systems. ETRAB4103 can also be used for navigation of military aircraft and unmanned aerial vehicles, as well as for tactical data links between multiple aircraft.

Working Principle

The ETRAB4103 uses an electronically controlled antenna array to allow for maximum flexibility in steering radio beams. It consists of multiple antenna elements, each with its own dedicated module containing signal processing electronics. These modules are interconnected using a radio system network in order to provide a wide beam-forming capability. Each module contains an RF amplifier and a phase shifter, allowing the beam to be steered to any direction necessary. The antenna array can also shift between narrow and broad beam angles depending on need. Due to its flexibility, this high-performance transceiver can be used in a variety of applications requiring low-noise performance at various frequencies.

The active electronically scanned array possesses superior properties such as wide angular coverage, scan speed, clutter rejection, and interference reduction in comparison to conventional RF antennas. It also has the advantage of allowing users to direct their antenna beam in any needed direction. The ETRAB4103 is designed to have an ultra-wideband performance and high dynamic range. It is also designed to operate in harsh environments such as high-temperature and high-humidity. Its robust design allows it to withstand input power levels ranging from -30dBm up to +29dBm.

Conclusion

The ETRAB4103 is an ideal choice for applications requiring a high-performance AESA transceiver. Its flexibility and high-performance characteristics allow it to be used in a variety of radio-frequency applications. The transceiver is suitable for use in the airborne electronic warfare segment as well as for navigation and communications systems. Moreover, it has a wide angular coverage, scan speed, clutter rejection, and interference reduction in comparison to conventional antennas. Therefore, the ETRAB4103 is an ideal solution for any application requiring high-end low-noise performance in a variety of radio-frequency applications.
