    The model AM1880-1960D268 surface-mount monoblock ceramic duplexer from Anatech Electronics is a compact solution for separating the transmit and receive bands of wireless communications base station transceivers. It features less than 3.4 dB insertion loss in the transmit band of 1850 to 1910 MHz with at least 49-dB rejection of unwanted signals and at least 11 dB return loss. It also exhibits less than 3.7-dB insertion loss in the 1930-to-1990-MHz receive band, with at least 54.5-dB rejection and at least 11 dB return loss. The compact duplexer measures just 4.6 x 23 x 6.5 mm but can handle input power levels to 2 W.
