    • Apparatus, method, and system example embodiments provide an improved RF front end (20) to simultaneously transmit and receive signals for cellular telecommunications. In an example embodiment, an apparatus comprises a tunable duplexer (40, 42, 44, 46, 48) selectively connected to an antenna (30, 32), configured to transmit and receive radio frequency communication signals in a group (G1, G2, G3, G4, G5) of at least two bands (B1 -B14, B17-B21, B23, B25, B26H, B27-B28); and a tunable transmit filter (40Tx, 42Tx, 44Tx, 46Tx, 48Tx) in the duplexer, capable of being tuned to have an inductance value approximately matching at least two inductance values corresponding respectively to pass the at least two bands in the group, each of the at least two bands in the group having a positive duplex offset and each of the at least two inductance values that correspond respectively to the at least two bands in the group, having an inductance value that approximately matches the inductance values corresponding respectively to the other bands in the group.
    • 装置,方法和系统示例实施例提供了改进的RF前端(20),以同时发送和接收用于蜂窝电信的信号。 在一个示例性实施例中,一种装置包括选择性地连接到天线(30,32)的可调谐双工器(40,42,44,46,48),被配置为发射和接收组(G1,G2, (B1-B14,B17-B21,B23,B25,B26H,B27-B28)的至少两条带(G3,G4,G5) 以及双工器中的可调谐发射滤波器(40Tx,42Tx,44Tx,46Tx,48Tx),其能够被调谐为使电感值近似匹配至少两个对应的电感值,以分别对组中的至少两个频带进行通过, 所述组中的至少两个频带具有正双工偏移,并且所述至少两个电感值中的每一个分别对应于所述组中的所述至少两个频带,其具有与分别对应于所述组合的所述电感值近似匹配的电感值 组中的其他乐队。
