The AB linear design operates over the 9.2-to-10 GHz radar frequency range, and has phase- and amplitude-control options for use in high-power systems that use conventional binary or phased array combining approaches for power levels to 10 kilowatts.
The amplifiers have pulse width and duty factor protection; thermal and load voltage standing wave ratio (VSWR) protection; optional digital interface for control and status monitoring; optional phase and amplitude control; and is a suitable building block for phased array systems.
The power electronics devices have peak output power of 1000 Watts of power gain of 60 db nominal power gain variation: of ±2 db (9.2-10 GHz); width of 0.25 to 100 microseconds; max duty cycle of 10 percent; max pulse droop of less than 0.5 db; and pulse rise and fall time of less than 60 nanoseconds.
The AB linear design has a typical input VSWR of less than 1.5:1; output load VSWR of less than 2:1; DC voltage input of 28 volts DC; and operates in temperatures from zero to 55 degrees Celsius.
These devices measure 9.6 by 6.8 by 2.15 inches and weigh 5 pounds. For more information contact Comtech PST online at www.comtechpst.com.
