CAP Wireless, Inc. (CAP) has unwrapped a new version of its RM022020 PA with enhanced performance that provides both excellent pulse fidelity and improved spurious response (typically –85 dBc). The RM022020, which was introduced in the fall of 2007, is the first in a series of high-power instrumentation amplifiers based on the company’s patented Spatium broadband spatial combining technology, according to CAP. Developed specifically for test environments that demand extreme bandwidth without switching or reconnecting amplifiers, this solid-state amplifier provides 20 Watts nominal saturated output power over an instantaneous band of 2 to 20 GHz. It offers high IMD performance, linearity, and gain flatness, without the warm-up, drift, or aging issues associated with TWTAs, said CAP.
The RM022020 comes in a compact rack-mount package and provides 45 dB gain (variable over 10 dB), enabling it to be driven with standard lab signal sources. It features excellent pulse fidelity, low noise figure (<8 dB) and safe operation into 10:1 VSWR. Designed for general lab use, the unit saves time and increases productivity by eliminating additional calibrations, reconfigurations, and errors associated with connecting or switching multiple amplifiers, stated CAP.
