RF Amplifier by AMETEK CTS

Note : Your request will be directed to AMETEK CTS.

The GT186 Series from Ametek CTS is a TWT Amplifier Series consisting of 3 amplifiers that operate from 6 to 18 GHz. They provide 200/300/500 W of output power with a gain of more than 53 dB and have a standard duty cycle of 6%. The amplifiers can handle up to 10 dBm of input power, have a pulse width range from 100 ns to CW, a rise/fall time of less than 45 ns, and spurious levels of -50 dBc. The TWTA series supports AM, FM, and Pulsed modulation formats.

The GT186 Series have integrated RF and hardware protection systems including high VSWR, over-current, and voltage protection as well as redundant thermal and airflow sensors to prevent the TWT from overheating. They also have a state-of-the-art touch screen interface that is sophisticated, comprehensive, and simple to use. The touch screen interface shows forward/reverse power indication, system status, and self-diagnostic information.

All the TWTA operating parameters are simultaneously available via the touch screen interface as well as over the remote bus. For remote operation GPIB, RS232, USB & Ethernet remote interfaces are included as standard. The amplifiers have BNC Female for pulse input with N-Type Female input and WRD650 output connectors. They are available in 19 inches, 6U Case, 680 mm deep rugged modular design and are ideal for multiple high frequencies, high power applications including but not limited to RF immunity testing.
