Filter Arrays Deter EMI/ESD

Relying on the company’s Centurion zener process technology, the CM1406 and CM1407 filter arrays provide both EMI and ESD protection in handsets that employ traditional packaging technology. The CM1406 is a four-channel filter in an 8-lead TDFN package that targets LCD and camera interfaces in clamshell wireless handsets. It employs a pi-style, 15 pF-200-15 pF configuration with flow-through routing for each channel. Filtering across all channels is achieved through a large ground pad on the bottom of the package that minimizes parasitic inductance. The device is able to attenuate signals at 35 dB over a frequency range of 800 MHz to 2.7 GHz. Other features include a cut-off frequency of 105 MHz. Using a 7.5pF-200Ω-7.5pF configuration and pin compatible with the CM1406, the CM1407 supports higher-resolution displays and imagers. It features a cut-off frequency of 210 MHz. Price for either device is $0.43 each/1,000. CALIFORNIA MICRO DEVICES CORP., Milpitas, CA. (800) 325-4966.
