Frequency control products manufacturer Precision Devices, Inc. (PDI), a member of the Avrio Technology Group, has added a new line of LC Filters -  Band Pass, Low Pass, High Pass and Notch LC filters.

With rapid prototyping, PDI offers a quick turn-around for any frequency from 5 MHz to 100 MHz. For higher frequencies, the engineering team works with customers to design the right custom filter. The initial standard line of Bandpass LC Filters has a 10% bandwidth in the frequency range of 5 MHz to 100 MHz.

These can have either 40dB (3:1 shape factor) or 60dB (3:1 or 2.5:1 shape factor) stopband attenuation characteristics and can work in a wide range of operating temperatures from -55°C to +105°C suited to industrial, military, and space applications. The return loss of the standard series is guaranteed to be 12 dB minimum across the band of interest. Typically this will be 15 dB minimum both on S11 and S22 measurements.

Filters requiring 40dB stopband attenuation are in a small SMD package while for filters requiring 60dB attenuation and higher selectivity, a larger SMD package is available. Custom packaging is also available, including through-hole and connectorized options. Manufacturing and reliability methods can be incorporated for products that require special hermetic and ruggedizing applications.
