Diplexers Come In Small Packages

These dual-band separators are said to offer exceptional reliability and superior performance for mobile communications designs such as AMPS-PCS, GSM-DCS and PDC-PHS. The LTF3216D-F Series of chip dual-band diplexers have a 1206 chip size (dimensions are 3.2 x 1.6 x 1 mm). The series offers a carrier frequency range from 800 to 2000 MHz to separate frequency bands downstream of the antenna for optimal flexibility in dual band RF cellular designs. Insertion loss is ≤ 0.5 dB with an average minimum attenuation of 20 dB in high or low bands.
