HIGHPASS DESCRIPTION

PFC has capability to design and manufacture Highpass filter from Dc to 30GHz and testing stop bands to Dc to 40GHz.

Lowpass filters are used to reject above a specified corner frequency to get any harmonic generation by amplifiers or mixers.

Our Highpass filter can be manufacture in different type of media. Not every filter design will be made with simple lumped elements but depending on frequency and Q needed to achieve your specification, Our engineers will select the proper media for your requirement. PFC has a printed circuit board capability on site and a fully equipped machine shop with a large selection of bar stock. We have developed and refined these processes to help achieve quick turn around even on the toughest jobs.

SCREENING

Commercial screening

All filters are temperature cycled per PFC internal quality assurance procedure. Filter are cycled and retested/ tune till they stabilized. When the filters have stabilize each filter is recorded and data is taken and supplied to the customer.

 

Military screening

Filters that are supplied to Military suppliers and the military will be design and cycled to

MIL-STD-202, Method F. Filter are cycled and retested/ tune till they stabilized. When the filters have stabilize each filter is recorded and data is taken and supplied to the customer.
