Anatech Electronics Inc, actively involved in design, manufacturing and supply of RF and Microwave components, just completed the design of their new Ceramic Monoblock Duplexers/Diplexers used in DCS and PCS communication. Low insertion loss and good rejection in a small package size are the most prominent features of these filters. AE1747D174 has Passband 1 @ 1805 MHz – 1880 MHz and Passband 2 @ 1710 MHz – 1785 MHz. Insertion Loss in both passbands is 4dB max, while the isolation is 30dB min. This part is built in a package size of 23.80 X 4.5 X 6.75 (mm) max.
