ALT6658LQ7 is an RF amplifier from the RF Amplifiers category. It is designed to allow high-efficiency power amplification at high power levels in both linear and digital modulation formats, making it suitable for several different applications. The amplifier is optimized for power levels up to +51 dBm and offers broad-band operation from universal single-ended or differential amplifier networks.This amplifier is assembled in the form of a fully shielded plastic enclosure, which enables it to easily integrate into larger RF systems. It incorporates an integrated DC power supply, temperature sensor, and power-saving circuitry. It also provides an extremely low EMI (electromagnetic interference) footprint, allowing it to be used in sensitive military applications.The ALT6658LQ7 operates with an input power range of -53 dBm to +51 dBm, and features internal linearization techniques that allow for reliable linear supply. This linear operation ensures that the amplifier does not saturate during operation. Furthermore, the amplifier has an adjustable gain that ranges from 10 dB to 30 dB, and peak power will be up to +51 dBm with a 3 dB compression point.When it comes to operation, the ALT6658LQ7 is designed to enable use in both linear and digital modulation formats. For linear operation, it utilizes an optimized bias current which can be adjusted via a voltage-controlled current source, allowing for reliable linear operation. Additionally, the internal combination of a digital pre-distortion circuit and automatic gain control loop enables efficient and consistent digital modulation performance. The digital pre-distortion circuit also allows for compensation of nonlinear amplifier distortion.Finally, the ALT6658LQ7 has a power draw of 1.9 A and a typical noise figure of 8.5 dB at the gain of 30 dB. This low power consumption and low noise figure make the amplifier ideal for use in systems that require high efficiency and low distortion, such as broadcast transmitters, medical imaging, radar, and industrial test equipment.
