MtronPTI has expanded its product portfolio to include ceramic filters that feature devices with frequencies from 300 MHz to 6 GHz with a 1-40% bandwidth.
The range includes mono-block duplexers, which are configured with several resonators. The technical advantages include removal of the additional parts such as combination circuits for combining resonators and external circuits for patterning or holes.
Applications for this include SATCOM, internet connectivity, telephone connectivity, point-to-point networks, point-to-multipoint networks, broadband access, LANs and WLANs.
An example of a device for WiMAX applications is CF2510R. It is a 3.5 GHz device with a 300 kHz bandwidth, featuring a 2.5 dB insertion loss, 1.0 dB of ripple and 13 dB return loss.
This 50W terminated filter operates over the temperature range of -40 to 85°C and provides 60 dB of attenuation at 3.95 and 3.1 GHz.
