Solid-state power amplifier for ground or surface X-band radar applications introduced by Comtech PST

Sept. 15, 2022
AB linear power amplifier operates over 9.2-to-9.7-GHz over an instantaneous bandwidth of 500 MHz, and is for traveling wave tube (TWT) replacements.

MELVILLE, N.Y. – Comtech PST Corp. in Melville, N.Y., is introducing the model BHCDP928978-4000 solid-state power amplifier for ground and surface X-Band radar applications.

The AB linear power electronics device operates over a 9.2-to-9.7-GHz frequency range over an instantaneous bandwidth of 500 MHz, and is for a traveling wave tube (TWT) replacement.

The amplifier design features self protection for load voltage standing wave ratio (VSWR), duty factor, pulse width, temperature, and graceful degradation in case of a RF power module failure.

A mean time between failures (MTBF) increase of 10 times that of a the TWT helps improved reliability and lower maintenance costs. Comtech supports custom configurations for power levels as high as 16 kilowatts.

The radar power amplifier offers output power of 4,000 Watts peak; power gain of 66 decibels nominal; pulse width of 40 microseconds typical; pulse rise and fall time of 20 nanoseconds typical; input VSWR of less than 1.5 to 1; and harmonics of -60 decibels relative to the carrier (dBc).

The power electronics device operates in temperatures from 0 to 50 degrees Celsius at the baseplate; works in humidity as high as 95 percent; meets MIL-STD-810F for resistance to the effects of shock and vibration; works at altitudes as high as 10,000 feet; uses RJ-45 Ethernet as its control interface; and uses SMA RF connectors. The unit measures 19 by 17 by 7 inches, and weighs 60 pounds.
