RF and baseband. Fig 3.1 Block diagram of RF part A generic, high-level functional block diagram of L705iX is shown in Figure 3.1-1. One antenna collects base station forward link signals and radiates handset reverse link signals. The antenna connects with receive and transmit paths through a Diplexer.
Page 15 ISDB-T 1seg receive path include an LNA, Mixer, IF Part and OFDM demodulator which are accommodated in ENT34606 IC. L705iX power supply voltages are managed and regulated by the PM6650 Power Management IC. This versatile device integrates all wireless handset power management, general housekeeping, and user interface support functions into a single mixed signal IC.

■ Insertion loss : This component is also in the receive and transmit paths; In the L705iX typical losses : UMTS2100_ Tx = 1.5dB, UMTS2100_ Rx = 1.8dB and UMTS800_ Tx =1.5dB, UMTS800_ Rx = 2.4dB ■ Out-of-band rejection or attenuation : The duplexer provides input selectivity for the receiver, output filtering for the transmitter, and isolation between the two.
