Taoglas Filter Technology

Taoglas has leveraged our extensive RF experience and materials expertise to create a line of filter technology products optimized to meet the needs of wireless device designers.

We offer high pass, low pass, band pass, notch, and diplex filters manufactured using a range of filter technologies to meet most RF needs.

Our filters are typically designed as surface mount components, but many can be connectorized for integration with external components.

The following filter technologies are available from Taoglas:

Ceramic Dielectric Filters (Discrete and Monoblock)
Ceramic dielectric filters are constructed of ceramic resonators of varying
dimensions, which can be either strung together in series with coupling capacitors
(in the case of discrete ceramic dielectrics) or formed into a single block (in the
case of monoblock ceramic dielectrics).

Advantages:

  • High power-handling capability
  • Good insertion loss
  • Configurable transition band roll-off
  • Good stopband performance
  • Low minimum order quantity
  • Fast prototyping (discrete)
  • Low cost (monoblock)

Low-Temperature Co-fired Ceramic (LTCC) Filters
LTCC technology allows miniature LC filter circuits to be constructed as a single
surface mount ceramic chip component.

Advantages:

  • Physically small
  • Low cost
  • Good insertion loss

Surface Acoustic Wave (SAW) Filters
SAW filters are formed on a single crystal to create a filter not made up of resonant
LC combinations.

Advantages:

  • Physically small
  • Fastest transition roll-off
  • Medium cost

Coaxial Filters

Coaxial filters are inline cable filters placed directly on the end of the antenna port to eliminate or reduce radio interference problems. They use standard RP SMA connectors and are easily screwed onto this standard antenna SMA connector.

Advantages:

  • It reduces out of band noise entering the receiver.
  • It reduces the antenna transmissions of out of band noise affecting other circuitry.
  • Has better insertion loss and stop band performance than competing LTCC or lumped element filters, while also maintaining good rejection at band edges.
  • Ideal for UAV applications

Taoglas announced it’s new RF filter division at Mobile World Congress Americas in September 2017.
