17.2 WCDMA Tx/Rx path and test points
WCDMA Tx path
The output signal from transmitter MAX2390 Pin2 travels to SAW filter
(BPF5), and RMPA2259 Pin2 sequentially. The boosted power coming from
RMPA2259 Pin8 passes through isolator (U954), duplexer Pin1 (U956), and
connector (Con7). At last, the RF signal is radiated via WCDMA antenna of
Halley.
WCDMA Rx path
RF signal in WCDMA, receiving from base stations via the WCDMA
antenna, passes through connector (Con7) and duplexer Pin3 sequentially.
MAX2391 Pin1 (U958), built-in LNA, receives the signal from duplexer. Then
the signal is transmitted to SAW filter (BPF6) and returns to receiver
MAX2391 again. After down converting the signal’s frequency and
transforming into IQ signals, the IQ signals from MAX2391 Pin20, Pin21,
Pin22, and Pin23 travel to baseband.
