Exodus Advanced Communications has developed a solid-state high-power amplifier (HPA) for mmWave pulsed radar, electronic warfare and radiated susceptibility testing, such as EMI-Lab/RS103. The instantaneous bandwidth of the AMP4065P-1KW amplifier covers the full K-Band, from 18 to 26.5 GHz, and provides at least 1 kW pulsed output power within a 3 dB peak-to-peak power flatness. The AMP4065P-1KW is unique: providing this level of power at mmWave frequencies from a solid-state HPA.

The HPA’s pulse capability supports radar systems with narrow or wide RF pulses and duty cycles to 5 percent; it has an 80 dB on/off ratio. The HPA uses a class AB design to achieve better than –20 dBc harmonics and –60 dBc spurious at rated output power. Gain can be controlled over greater than a 20 dB range.

The AMP4065P-1KW has extensive control and monitoring functions, including the gain control and optional calibrated power monitoring, using either the large 7 in. color display or via remote control. The color touchscreen shows the forward and reflected power, VSWR in real time, system voltages and currents and the internal system temperature and operating temperatures of the HPA module heat sinks. These performance parameters are also available via the remote interface.

Rack integrated, the AMP4065P-1KW uses type K (2.92 mm) female connectors for the RF input and optional RF sampling ports. To handle the high output power, the output connector is a WR42 waveguide flange.

Exodus Advanced Communications’ products use LDMOS, GaN HEMT and GaAs technology, with a good share of the devices manufactured by the company. In addition to HPAs, Exodus designs low noise amplifiers, modules and multi-band systems for applications operating from 10 kHz to > 51 GHz.
