Newbury Park, CA — CAP Wireless has announced a new version of its RM022020 power amplifier (PA) with enhanced performance that provides both excellent pulse fidelity and improved spurious response (typically -85dBc).
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 (shown in illustration).
Developed specifically for test environments that demand extreme bandwidth without switching or reconnecting amplifiers, this solid-state amplifier provides 20 W nominal saturated output power over an instantaneous band of two to 20 GHz. It offers superior intermodulation distortion (IMD) performance, linearity, and gain flatness, without the warm-up, drift, or aging issues associated with traveling wave tube amplifiers (TWTAs).
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 (less than 8 dB) and, with safe operation into 10:1 voltage standing wave radio (VSWR), is highly load tolerant. 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.
Spatium broadband spatially combined power amplifiers from CAP Wireless obsolete today's power amplifiers and make the unachievable a reality. Spatium amplifiers excel when extremes of bandwidth and power are demanded. The patented technology, which incorporates a coaxial antipodal finline structure within a proprietary spatial combining architecture, provides a breakthrough product that combines the stability of solid-state amplifiers with exceptionally broad bandwidth and high power.
Spatium's unique circuit topology enables a highly manufacturable platform that leverages component commonality between different models. This eliminates time-consuming redesigns for each variation and increasing repeatability unit-to-unit, resulting in significant time-to-manufacture cost-savings for customers. Spatium power amplifiers are uniquely positioned to meet the demanding specifications of applications such as electronic counter measures (ECM), laboratory instrumentation, and electromagnetic compatibility/electromagnetic interference (EMC/EMI) test, as well as narrower band applications like radar, microwave imaging, and satellite communications.
