Duplexers offer high linearity for CDMA and LTE applications
Thanks to the high linearity achieved, the sensitivity in the input paths is increased. This allows developers of mobile phones to significantly simplify the architecture of the RF input circuit because additional components for linearization are not required.
B7654 Duplexers are designed for the 824 to 849 MHz frequency band in transmit mode (TX) and from 869 to 894 MHz in receive mode (RX). Attenuation of up to 57 dB is attained between the transmit and receive bands. Interfering GPS frequencies are attenuated by 40 dB.
The B7928 is designed for the 777 to 787 MHz frequency band in transmit mode (TX) and from 746 to 756 MHz in receive mode (RX). Attenuation of up to 62 dB is attained between the transmit and receive bands. Interfering GPS frequencies are attenuated by 45 dB.
The duplexers have dimensions of only 2.5 x 3.0 mm². Series production is scheduled to begin in the second quarter of 2012.
