In the contest for control of the electromagnetic spectrum, electronic jamming stands as a core method of electronic warfare (EW). It operates by emitting high-power electromagnetic signals to suppress, deceive, or disrupt an adversary's radar, communication, and navigation systems, thereby stripping them of their detection, tracking, and communication capabilities. The RF power amplifier (PA) plays a pivotal role in this process, amplifying jamming signals to the necessary power levels to ensure effective coverage of the target frequency bands.

Coreal specializes in RF power amplification technology, offering products that span a wide frequency range from DC to 50 GHz with output power reaching up to 5,000W. Utilizing comprehensive technology platforms—including LDMOS, GaAs, and GaN—Coreal provides reliable power amplifier modules and customized solutions for applications such as electronic warfare, electronic countermeasures (ECM), and anti-drone systems.

Technical Requirements for Jamming Power Amplifiers

1. Wideband Coverage – Jammers must contend with signals across various frequency bands, requiring power amplifiers capable of multi-octave wideband operation. For instance, a 6–18 GHz wideband amplifier can cover multiple radar bands simultaneously, enabling multi-functional capability within a single unit.
2. High Power Output – The effective jamming range is directly linked to transmit power. Output power for jamming amplifiers ranges from tens of watts to several kilowatts, depending on the specific target and platform type.
3. Continuous Wave (CW) Capability – Unlike radar amplifiers that typically operate in pulsed modes, most EW jamming systems require amplifiers capable of Continuous Wave (CW) output to ensure sustained signal suppression.
4. High Linearity and Fast Response – For scenarios such as deception jamming—which require the precise replication of signal waveforms—amplifier linearity and phase consistency are critical.
5. Miniaturization and High Environmental Adaptability – Systems must meet rigorous environmental standards regarding temperature extremes, vibration, and salt spray resistance. Typical Jamming
