Travelling wave tube (TWT) instrumentation amplifiers for test and measurement and EW introduced by CPI
PALO ALTO, Calif. – Communications and Power Industries (CPI) International Inc. in Palo Alto, Calif., is introducing two K- and Ka-band travelling wave tube (TWT)-based instrumentation amplifiers for test and measurement, communications, electronic warfare (EW), and radar.
The PTCM1017 and PTCM1027 feature higher gain and efficiency performance than solid-state amplifiers. Other applications include RF component testing, electromagnetic compatibility (EMC) testing, and radiated immunity testing.
With a frequency coverage of 18 to 26.5 GHz (K-band, PTCM1017) and 26.5 to 40 GHz (Ka-band, PTCM1027), the amplifiers offer a power output exceeding 100 Watts continuous wave, and can also be pulsed using an internal grid modulator.
Operating features include self-test, comprehensive fault diagnosis, Ethernet remote control and monitoring, and modular plug-and-play field replaceable printed circuit boards. The amplifiers also include TWT and power supply protection.
An Ethernet graphic user interface enables connection to any PC or laptop with a standard browser. This functionality enables CPI to offer customers on-demand support by remotely connecting to the amplifier to provide in-depth diagnosis and care, should it be needed.
The protection systems monitor critical performance parameters to ensure the product is not damaged in the event of incorrect operation. The TWT heater, grid and cathode voltage are continuously monitored and voltage standing wave ratio (VSWR) protection is provided.
Designed and built to ISO9001 quality certification, the construction of the PTCM1017 and PTCM1027 is based on a modular 6U system that offers different configurations.
The amplifiers are of rugged construction, with vibration testing to Military Standard 810G-Transport. The operating temperature can accommodate temperatures from 0 to 40 degrees Celsius with 80 percent maximum humidity.
