500 W Pulsed X-Band GaN PA: AMP4002P

September 14, 2015

9M43sProdImgx250Exodus Advanced Comm.  has released the latest in a family of very high power, X-Band solid-state amplifiers. With a GaN, Class AB design to achieve maximum output and high efficiency, the AMP4002P delivers 500 W pulsed output power, 400 W minimum, from 9.1 to 9.5 GHz. The pulse width can range from 0.35 to 50 µs, measured at the 50 percent transitions, with a 20 percent duty cycle, 5 kHz pulse repetition frequency and 75 ns rise and fall times. The amplifier has a minimum power gain of 56 dB with flatness of 2 dB peak-to-peak (maximum).

The AMP4002P incorporates an internal filter to keep harmonics better than -60 dBc. Built-in functions include TTL gate control inputs, RF output detector and an over-temperature alarm. Internal circuitry ensures the system is fully protected against all failures. The power amplifier (PA), which is assembled in a 19-inch wide housing, features a state-of-the-art controller capable of supporting Ethernet TCP/IP, RS422/485 and remote Bluetooth connectivity. A front panel touchscreen is available as an option.

The AMP4002P has been tested and fully qualified for the following environmental conditions: operating temperature from -20° to +55° C, humidity to 95 percent at 40º C, shock and vibration per MIL-STD-810F, altitude per MIL-STD-810F and EMI/EMC per MIL STD 461E.

Exodus Advanced Communications designs and manufactures solid-state RF power amplifiers covering frequency bands from 10 kHz to 40 GHz, achieving module output power greater than 1 kW and complete systems exceed 10 kW. Other standard X-Band products include a 400 watt PA covering 9.5 to 10 GHz and a 1 kW, 9.1 to 9.5 GHz design. Exodus PAs integrate discrete LDMOS, GaAs and GaN devices with ceramic substrates using chip and wire (hybrid) assembly processes. In-house capabilities include RF circuit, system mechanical and electrical and digital circuit design, control software development and prototype verification.
