43-46GHz 10W 20W Q-band Radar Power Amplifier for Communication

ZD-PAR-43/46G-10/20W

This 43–46GHz Q-band radar power amplifier is designed for high-performance communication and signal processing applications, offering both 10W (+40dBm) and 20W (+43dBm) output variants. Operating across the 43–46GHz frequency range with optional 950–1550MHz input support, it delivers a fixed 50dB gain with 0–20dB adjustable attenuation (0.1dB steps), ensuring precise signal control.
The amplifier maintains ±0.5dB/24h gain stability and low phase noise performance, with harmonics and spurious emissions ≤-60dBc for reliable operation. Powered by 220VAC with forced air cooling, it features optional communication interfaces (LAN/RS485/RS422/RS232) for remote monitoring. Compact and robust, it is ideal for demanding RF systems requiring high linearity and efficiency.
