through connector (Con6) and T/R switch Pin15 (U902) sequentially. There are

three output pins of T/R switch, including Pin2, Pin4, and Pin5. The output

path which RF signal is transmitted depends on band selection of T/R switch.

In GSM900 band, the output signal which is transmitted from T/R switch

Pin2 passes through SAW filter (BPF1) and matching circuits sequentially.

Upon RF2722 (U901) receiving the signal, it is amplified in the Low Noise

Amplifier (LNA) of the receiver, down converted the signal’s frequency and

transformed into IQ signals. The IQ signals from RF2722 Pin20, Pin21, Pin22,

and Pin23 travel to the transceiver RF6001 (U900). The transceiver RF6001

transfers the signals to the baseband signals.

In DCS1800 band, the output signal which is transmitted from T/R switch

Pin5 passes through SAW filter (BPF4) and matching circuits sequentially.

Upon RF2722 (U901) receiving the signal, it is amplified in the Low Noise

Amplifier (LNA) of the receiver, down converted the signal’s frequency and

transformed into IQ signals. The IQ signals from RF2722 Pin20, Pin21, Pin22,

and Pin23 travel to the transceiver RF6001 (U900). The transceiver RF6001

transfers the signals to the baseband signals.

In PCS1900 band, the output signal which is transmitted from T/R switch

Pin4 passes through SAW filter (BPF1) and matching circuits sequentially.

Upon RF2722 (U901) receiving the signal, it is amplified in the Low Noise

Amplifier (LNA) of the receiver, down converted the signal’s frequency and

transformed into IQ signals. The IQ signals from RF2722 Pin20, Pin21, Pin22,

and Pin23 travel to the transceiver RF6001 (U900). The transceiver RF6001
