Ceramic duplexers shrink to fit smaller handsets
Epcos has scored another success in miniaturising ceramic CDMA duplexers.
Epcos has scored another success in miniaturising ceramic CDMA duplexers. Insertion height in particular has been significantly reduced, so that dimensions are now only 19 x 6.5 x 2.7mm for the B59959N1927A360 and 14 x 6.5 x 2.2mm for the D3014. In comparison with duplexers currently in use, component size (volume) has been reduced by about 65% without compromising electrical performance.
The tried and tested properties of microwave ceramic filters include a very low temperature coefficient, extended temperature range (-40 to +85C) and high power compatibility.
In view of their rugged design, some microwave ceramic duplexers are also being tested to automotive specifications.
