RF Filters
-
CTS develops and manufactures high-end radio frequency (RF) filters used by various technologies to block out or filter certain signal frequencies. In 1982, CTS invented the ceramic monoblock, and ever since, our ceramic RF filters have been setting the industry standard in terms of lowest insertion loss, attenuation /rejection/isolation, Q-factor, size, power handling, and transition slope. Our portfolio includes band-pass filters, notch filters, low-pass filters, delay line filters, diplexers, duplexers, and triplexers/multiplexers.

Servo And VFD Filters
-
Operation of PWM-driven motors – servo motors and variable frequency drives (VFD) – causes several problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation. PWM motors also are a major source of EMI in equipment. These motor drive systems use pulsed power to drive the motors. As we are aware, the sharp edges of the pulses inevitably include high frequency components which can couple or radiate as noise to other parts of your system and cause unreliability, communication/control problems and EMC compliance issues.

Active Voltage Probes
-
Engineers must commonly probe high-frequency signals with high signal fidelity. Typical passive probes with high input R and C provide good response at lower frequencies, but inappropriately load the circuit, and distort signals, at higher frequencies. Active voltage probes feature both high input R and low input C to reduce circuit loading across the entire probe/oscilloscope bandwidth. With low circuit loading, and a form factor that allows probing in confined areas, the active voltage probe becomes the everyday probe for all different types of signals and connection points.
