Upgrade Existing Amplifiers
This new concept called “Subampabilty” enables labs to upgrade their existing “S” series (1 to 800 W, 0.8 to 20 GHz) amplifiers to higher power without purchasing new amplifiers. Once an initial upgrade is performed, the sky’s the limit. Models 20S4G11A (20 W, 4 to 10.6 GHz) and 35S4G8 (35 W, 4 to 8 GHz) are building blocks that can easily be expanded by adding sub amps and controller/combiner units. The 20S4G11A can expand to 40, 60 or 80 W, while the 35S4G8 can grow to 60, 90 or 120 W.

RF Amplifiers
The JCA line of RF amplifiers includes over a dozen models with an average gain tracking of ±0.75 dB and ±1.5 dB gain matching across a 2 to 18 GHz bandwidth. The high performance and reliability of these amplifiers is primarily achieved as a result of an automated assembly process using precise pick-and-place machinery and automatic wire-bonding. Minimizing gaps between components and maintaining efficient, consistent wirebond lengths in the assembly process yields significantly improved gain and phase tracking performance unit-to-unit, and often reduces RF tuning times by 30 percent.
