A surface-mount, monoblock ceramic duplexer dubbed the model AM1880-1960D268 serves wireless-base-station transceiver communication applications from 1850 to 1960 MHz. In terms of transmit-to-receive response, the 50- Ω duplexer exhibits insertion loss of 3.4 dB or less from 1850 to 1910 MHz and minimum return loss of 11 dB. It provides attenuation ranging from 45 dB for DC to 1000 MHz to 38 dB for 2040 to 2100 MHz. Regarding antenna-to-receiver response, it exhibits insertion loss of 3.7 dB or less from 1930 to 1990 MHz and attenuation ranging from 51 dB for 1850 to 1910 MHz to 30 dB from 2150 to 2210 MHz. The duplexer provides rejection of at least 54 dB in the transmit band and 49 dB in the receive band. It handles RF input power to 2 W. The AM1880-1960D268 measures 4.6 x 23 x 6.5 mm.
