What is an integrated passive filter?

Traditional filter solutions are based on discrete ceramic or silicon passive components, both of which can be expensive and difficult to integrate into ever-smaller sizes. Recently, a new type of RF package has emerged, one that is based on laminating multiple layers of organic materials together. This approach (multi-layer organic or MLO), combining thin organic dielectric materials embedded into substrates, has been applied to a variety of RF products, including tightly integrated RF front-end-modules and filters. It has proven to be more effective than other alternatives, such as low temperature co-fired ceramic (LTCC) and conventional laminate substrates, which have difficulty integrating into shrinking sizes and silicon geometries.Further, LTCC is a costly process that has had temperature-related failures with common PCB-type substrate materials, and the components based on LTCC suffer from performance drift with temperature changes. MLO filters offer a superior solution with performance that is consistent across the specified temperature ranges.In addition to temperature, MLO devices provide significant electrical, physical and reliability advantages over traditional discrete RF or LTCC solutions.

Passive filter types

  1. Low-pass filters attenuate or suppress signals with frequencies above a particular frequency called the cutoff or critical frequency. For example, a low-pass filter (LPF) with a cutoff frequency of 40 Hz can eliminate noise with a frequency of 60 Hz.
  2. High-pass filters suppress or attenuate signals with frequencies lower than a particular frequency, also called the cutoff or critical frequency. For example, a high-pass filter (HPF) with a cutoff frequency of 100 Hz can be used to suppress the unwanted DC voltage in amplifier systems, if desired.
  3. Band-pass filters attenuate or suppress signals with frequencies outside a band of frequencies. They are common in TV or radio tuning circuits.
  4. Band-reject, or notch filters attenuate or suppress signals with a range of frequencies. For instance, a notch filter can reject signals with frequencies between 50 Hz and 150 Hz.
