GaN small-form-factor power amplifier to replace TWTs and microwave power modules introduced by Comtech PST
MELVILLE, N.Y. – Comtech PST Corp. in Melville, N.Y., is introducing the model BME69189-100 small-form-factor solid-state power amplifier module for replacing traveling wave tubes (TWTs) and microwave power modules (MPMs) in legacy aerospace and defense electronics.
The integrated RF gallium nitride (GaN) model BME69189-100 provides 6 to 18 GHz at 100 Watts, and is for communications, electronic warfare (EW), and radar transmitter systems where space, cooling, and power are limited.
The RF GaN solid-state power amplifier module offers ultra wideband operation; full power across the entire bandwidth; is rugged and reliable; is compact and lightweight; offers low harmonic distortion; has low-voltage operation; tolerates soft failure with graceful degradation; offers integrated RF power reporting; and operates with 28- or 270-volt DC input.
The power electronics devices offers AB linear operation; maximum input and output voltage standing wave ratio (VSWR) of 2.0 to 1; will output power into 2:1 load of more than 70 Watts; offers over-current fault built-in test; operates at less than 30 Watts DC and standby power; offers typical efficiency of 10 percent; and uses SMA Female field replaceable connectors for input and output.
These power modules operate at baseplate temperatures from -40 to 75 degrees Celsius; resist the effects of shock and vibration per MIL-STD-810F; measure 8 by 6 by 2.5 inches; and weigh 5.5 pounds.
