MELVILLE, N.Y. – Comtech PST Corp. in Melville, N.Y., is introducing the model BMCAP99109-1500 gallium nitride (GaN) solid state power amplifier module for X-band radar applications.

The X-band power amplifier operates at frequencies of 9 to 10 GHz, 9.0-10 GHz, and offers typical peak output power of 1500 Watts. The AB linear design features pulse width and duty factor protection as well as thermal and load voltage standing wave ratio (VSWR) fault monitoring.

The gallium nitride amplifier has an optional digital interface for control and status monitoring, and offers fast blanking and low phase noise.

The amplifier offers power gain of 62 decibels nominal; power gain variation of ±2 decibels; pulse width of 0.25 to 100 microseconds; duty cycle of less than 6 percent; pulse droop of less than 0.015 decibels per microsecond; pulse rise & fall time of less than 50 nanoseconds; input VSWR of less than 2:1 output load VSWR of less than 2:1.

The amplifier has an RF input sample of -15 decibels relative to carrier (dBc); RF Pulse of on-off isolation of more than 110 dBc; DC voltage input of 28 volts DC; DC supply current of 12.5 amps RF to DC; and efficiency of 25 percent.

The RF and microwave amplifier operates in temperatures from -40 to 65 degrees Celsius at the baseplate; operates in humidity of 0 to 95 percent non-condensing; offers resistance to the effects of operating shock and vibration per MIL-STD-810F; and operates at altitudes to 30,000 feet.

The amplifier measures 9.6 by 6.8 by 2 inches, and weighs 5.5 pounds. For more information contact Comtech PST online at https://comtechpst.com.
