摘要：

An ultra-miniature duplexer (5 x 8 x 2.2mm(3)) consisting of two FEAR filters and nine passive components operating at 1900MHz is described. The minimum insertion loss for the Tx and Rx bands is better than -3dB. Isolation between the Tx and Rx ports exceeds 50dB over most of the Tx band and 46dB in the Rx band. The FEAR filters handle up to 2W throughout the passband.
