Gallium nitride RF and microwave amplifier for X-band radar introduced by Comtech PST

Comtech PST Corp. in Melville, N.Y., is introducing the model BPMC928109-1000 gallium nitride (GaN) RF and microwave amplifier for X-band radar applications. The AB linear design operates over the 9.2-to-10.0 GHz radar frequency range. The amplifier design features options for control of phase and amplitude to allow for integration into high-power systems that use conventional binary or phased array combining approaches for power levels to 10 kilowatts. Features include AB linear gallium nitride (GaN) technology; high output power dynamic range; RF input and output sample detectors; 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 building block for phased array systems. Performance specifications include frequency range of 9.2 to 10.0 GHz; peak output power of 1000 watts; power gain of 60 dB nominal; power gain variation of ±2 dB (9.2-10 GHz); pulse width of 0.25 to 100 microseconds maximum; duty cycle of 10 percent max; pulse drop of less than 0.5dB; Pulse Rise and Fall Time of less than 60 nanoseconds typical; input VSWR of less than 1.5:1; and output load VSWR of less than 2:1. These devices measure 9.6 by 6.8 by 2.15 inches, and weigh five pounds. For more information, visit Comtech PST online at www.comtechpst.com.
