New 15kW S-Band 2.7-2.9 and 2.7-3.1 GHz GaN Pulse SSPA System for Air Traffic Control (ATC) Primary Surveillance RADAR

DVB-TECH GaN based S-band Pulse Solid State Power Amplifier for Air Traffic Control Radars (ATC). The highly  efficient design is the ideal replacement for TWT amplifiers used in electronic warfare (EW), RADAR and SATCOM applications. It offers 15kW of saturated power across a 2.7 to 2.9 (optionally 2.7 to 3.1) GHz frequency band with maximum reliability and long service life.

The modular design includes ten (10) how-swappable SSPA modules in N+2 soft fail configuration; the loss of one (1) or two (2) SSPA modules will not result in an output power level degradation.  Passive combining/switching is employed to avoid RF output power interruptions.  A redundant AC/DC power supply system with hot-swappable modules is also included.

The SSPA system also features a number of monitoring and self-protection circuits including input overdrive, forward power, reflected power, high pulse width, high PRF and over temperature. Additionally, the system is equiped with an output waveguide isolator.

The system controller provides a user friendly interface for monitoring and control of the complete SSPA system as well as the individual SSPA modules.  A front panel display provides the user with local monitoring and control, while Ethernet and RS485 interfaces provide the user with local/remote monitoring and control via PC GUI, Web GUI and SNMP.
