The new high frequency ceramic filters are available in surface mount technology, and are designed with excellent matching for 50Ω communication systems where space and weight are critical design criteria.
The 1.85mm subminiature ceramic filter is part of a new family of ultra-small profile filters available in Surface Mount Technology (SMT) designs. These small profile ceramic filter designs offer solutions that are lighter weight, and have reduced X Y Z dimensions to better meet customer requirements.
Microminiature filters are a new family of ultra-small bandpass notch filters designed to offer new options of lighter weight, reduced size ceramic filters for specific customer requirements. These filters are manufactured from UHF up to 6.5 GHz with a 50% overall size reduction, allowing for design flexibility beyond traditional ceramic styles.
MtronPTI’s SA0068 7-way Switched Filter Bank provides transmitter harmonic management with at least 30 dB of 2nd harmonic rejection in seven selectable frequency bands from 30 MHz to 512 MHz. With a low insertion loss of less than 1.3 dB, 30 Watts of power handling and a small, 65 mA current drain max, the SA0068 is ideal for applications such as multiband tactical radios and portable radio power amplifiers.
The 8LBCRLC-150/1575/20-O is a hybrid ceramic/LC GPS filter with a DC bypass and lightning protection. It has a center frequency of 1575+2 MHz, <1 dB insertion loss, <200 mA current, <4.5 dB insertion loss, <1.5:1 in/out VSWR, 3 dB bandwidth at 25-30 MHz, and more.
AM3023 is a miniature filter bank module with sub-octave filters covering the 100 MHz to 6000 MHz frequency range with a full 80-MHz overlap from 400 to 6000 MHz. The device contains a bypassable amplifier section and supports both transmit and receive applications.
MCV Microwave’s NPX787M is a ceramic notch filter that covers the DC-787 MHz frequency range. It’s been designed to provide precise signal separation between LTE 800 and DVB-T in order to minimize potential interference due to close operating vicinities.
API Technologies (Utilizing the combined heritage of CMT, Spectrum Microwave, Salisbury Engineering, and FSY Microwave) has developed and produced high quality, High “Q” Filters since 1983, and assisted major wireless carriers and installers with co-location solutions at BTS sites. Key performance features include Low PIM (passive intermodulation), high isolation and low insertion loss.
