High Frequency RF Power Supplies – CX Series

The CX platform has proven to be the benchmark in the semiconductor industry for value and reliability. These high frequency (HF) generators operate at a single frequency from 3.39MHz to 30MHz. A frequency agile option allows fast frequency tuning in a range +/-10% of the center frequency.

The unsurpassed MTBF of the CX series brings the cost of ownership to a very low level. These generators were the first to incorporate Comdel’s patented “S” technology in power amplifier design.  This design enhances system stability and increases the life of the RF delivery system.

Performance
The CX high frequency series is available at 10 kW for frequencies 3.39 to 20 and 8kWfor frequencies above 20-Mhz to 30Mhz, and frequency agile capability up to 10% bandwidth. The CX series provides precise, repeatable power control with ultra-stable output. The solid-state design provides low cost of ownership with high reliability.
cx-series
