.4. Description of STR250R01C RHU

[Forward Path] The signal from CDMA BTS is fed to the RF link antenna port of RHU. First, RHU Filter rejects the unwanted signal. Then LNA and Up-down converter make gain for transmitting. Combiner combines the signal with the modem signal (360MHz). The combined signal gets transmitted to RU via optical cable.

[Reverse Path] The CDMA RVS signal input from RU through the optic module is separated into RF and modem signal, and then RF RVS module performs optic AGC and RVS HPA makes large signal level for transmitting. Finally RHU Filter rejects the unwanted signal and RHU link antenna outputs RVS RF signal. The RF signal then is fed to the BTS.

4.2.4. Description of STR250R01C RU

[Forward path] The RF and modem combined signals sent from the optic module of RHU is first divided into RF and modem signals at Divider in RU, then the 1900MHz Tx RF signal is amplified and filtered at the RFBS module, 850MHz Tx RF signal is amplified and filtered at the RFCHS module. The modem signal is conveyed to CPU of NMS controller through FSK modem. CDMA signal is reduced by the Crest Factor passing through the CFR FPGA digital board inside RFBS and RFCHS. This technology enables reduction of PAPR for CDMA signal increasing HPA efficiency. A higher efficiency HPA allows using a smaller enclosure with lower power consumption while decreasing OPEX for the service provider. The CDMA RF signals from the RFBS module is linearly amplified up to high power level on HPA, passed through the Front-End Filter Unit, and finally transmitted through an antenna.

[Reverse Path] CDMA Rx signals incoming from 1900MHz or 850MHz antenna are first passed by the Front-End Filter Unit, amplified by a low noise and high gain amplifier, filtered in RRBS(for 1900MHz band) or RRCHS(for 850MHz band), and combined with modem signal at combiner(RRCOM). The combined signal is then transmitted to RHU through the optic module.

6.9. Additional features

6.9.1. ASD (Auto Shutdown) Function

1. If the power level is above the shut down level for longer than 1 second, turn off HPA.

2. During shutdown state, monitor RU input power. If the level is below 5dB from shut

down level, turn on HPA automatically.

3. Monitor HPA output power in normal operation, and monitor RU input power during

shut down.

6.9.2. ALC (Auto Level Control) Function

1. If the power level reaches the ALC level, prevent from transmitting higher than ALC level

by using ATT control.

2. When power level goes down under ALC level, ALC ATT will be decreased until it

becomes 0. It will decreased 1dB per about 500 mS or 1 sec.

Longer than 1 sec, HPA off

6.9.3. Center Channel Selection

RHU and RU can cover only 25MHz band width. For Cellular band, it will be OK, But for PCS, user

have to choose proper center channel of device. It seems to sliding window.

User can specify center channel as following table:
