WCDMA Bias-T description

R

A4

The Bias-T used in the Nokia Siemens Networks WCDMA Antenna Systems is an integral component of the WCDMA Masthead Amplifier (MHA). There are two versions of Bias-T available: Bias-T with VSWR (voltage standing-wave ratio) and non-VSWR Bias-T. Bias-T has two primary functions. It provides: • Power to the Masthead Amplifier by injecting DC power into the RF feeder centre conductor, so separate DC cabling is not needed • Fault monitoring of the antenna line VSWR (voltage standing-wave ratio) and Masthead Amplifier, forwarding alarm signals to the base station antenna filter unit (WAF) The Bias-T transfers DC power via the antenna coaxial cable to the MHA connected to the antenna line. The Bias-T combines DC and RF energy onto the same coaxial cable and provides RF isolation toward the DC voltage supply and DC isolation towards the BTS. The BTS TX power is fed through the Bias-T. The VSWR alarm function indicates that the antenna, MHA, feeders or jumpers have developed problems which impair their functioning. The Bias-T with VSWR can be installed to a WCDMA Antenna System without an MHA as a stand-alone unit to provide lightning protection and VSWR monitoring.

Flexi WCDMA BTS Internal Bias-T VSWR Tuning

A4

Choosing the Antenna → Tune VSWR Threshold menu item opens the Tune VSWR Threshold dialog box, where you can tune VSWR alarm threshold values for antenna filters inside RF modules.

R

The VSWR treshold tuning is used for defining values when an alarm notification needs to be sent for a minor problem of an antenna line condition (decreased condition) and for a major problem condition (cell blocking). The VSWR threshold tuning can be also used (indirectly) to find out the actual VSWR value by changing the values and monitoring alarms.

WCDMA Dual MHA monitoring and alarms

A4

•If the MHA unit fails, a bypass mode ensures that the antenna line sector continues operating

R

•Alarms are sent to the BTS via the DC feeders so if the power to the MHA is switched off the alarms are switched off •If MHA power is lost, the MHA no longer amplifies the Rx signal, but the by-pass operation is still able to pass through the Rx path (with minor loss). •The MHA has an operational current 'window' and providing the current consumed is within this window and within the specified DC voltage range, the MHA operates correctly •When the monitored MHA current consumption is outside this window, an MHA alarm is activated •The BTS operating software confirms the alarms and performs a recovery action applicable to the version of BTS operating software being used •To identify the specific software recovery action, please refer to the BTS Software User Manual for information •An MHA alarm alerts if the MHA Low Noise Amplifier (LNA) is defective or outside the operational limits Note •If open or high impedance exists along the antenna line supplying the MHA DC supply, this indicates a VSWR alarm condition •If an MHA alarm is activated, the cause of the alarm must be identified •Once the cause is clearly identified, the appropriate corrective actions can be performed to correct the fault

following functions: • Amplifying the uplink signal received from the TX/RX antenna with a low noise figure. • Feeding the overall Node B downlink signal to the TX/RX antenna • The TMA is an optional but highly recommended unit as it compensates cable losses in the uplink and thus ensures lower noise disturbance. • High selectivity filters ensure high TX/RX separation, enabling the reception of low signal levels in the uplink. It therefore improves link quality and link availability at the cell borders

R

A4

The TMA is always installed outside the Node B rack/shelter and close to the antenna, thus achieving fixed sensitivity independently of the feeder cable length.

Concept of TMA and DTMA

•one duplexer subsystem •a triplexer

A4

The TMA module consists of

R

•a low-noise amplifier (LNA) with a fail-safe path and a bias & signaling board •The transmit path consists of the TX part of the duplex filters •The receive path consists of the RX part of the duplex filters and contains the LNA •The triplexer combines the TX and the RX path with the TMA signaling path (e.g. alarms). Therefore only one feeder cable is required between the TMA and the Node B •The TMA is supplied with +12 V DC through the feeder cable from the Node B The LNA within the TMA has two parallel gain elements: •If a single failure occurs, operation continues with reduced gain •If both gain elements fail, or the supply of the TMA fails, the LNA is bypassed by a fail-safe switch. The DTMA module consists of •two RF ports •a duplexer subsystem •a triplexer •an LNA with a fail-safe path and a bias & signaling board •For each sub-module, signaling and DC power supply are provided through the associated feeder cables from the Node B

Pole Mounted DTMAF

R

A4

The hose clips surrounds the pole and are fitted into the corresponding openings of the mounting plate (see rear view of the devices). This is the situation just before tightening the hose clips. For the mounting, the following steps can be generally recommended. First connect the DTMAF / DTMARETF to the antenna feeder cable. Take into consideration that the antenna feeder often is very stiff and rather heavy. The position of its coaxial connectors therefore often determines the position of the DTMAF / DTMARETF on the pole. 1. Place the DTMAF / DTMARETF in its final mounting position at the pole. 2. Secure the unit with a tensioning belt. 3. Open the hose clips by pressing the “button” at the end of the clip lock and then smoothly pull out the perforated metal band. 4. Move the metal band of the hose clip gently into the openings of the mounting plate. 5. Close the hose clip loosely around the pole. 6. Tighten the hose clip screws carefully, but do not over-tighten. 7. Remove the tensioning belt. 8. Connect the DTMAF / DTMARETF first to the antenna feeder cable (NodeB) and then to the antenna jumper cable (ANT). The torque must be 25 Nm (18.5 ft lb). 9. Connect the protective earthing conductor with the DTMAF / DTMARETF ground screw. Tighten the connection to a torque of 5 Nm (3.7 ft lb). 10. The use of self-vulcanizing tape as an environmental protection of the connectors is recommended. Pay attention to the thermal dimensional changes of the antenna feeder cables. If the antenna is equipped with a RET module, install the DC power / data cable between the module and the 8 pole circular connector of the DTMARETF. The required cable will be delivered with the RET module together.

WMHD WCDMA Dual MHA (RAS06)

R

A4

WMHD MicroMHA comprises two identical amplifiers in one compact integrated package which is easy to transport and install. A state of the art Low Noise amplifier design provides a nominal 12 dB of gain, compensating feeder loss and improving coverage. In the unlikely event of component or power failure, a bypass path allows the BTS to continue operation. Power is fed via the feeder cable, in Flexi BTS no BiasTs are needed, WMHD gets it’s power and control directly from BTS. With Ultrasite one BiasT is needed. WMHD has also RET connector for remote antenna tilt adjustor, RTA. WMHD Mast Head Amplifier is upgrade on WMHC. WMHD adds RET output connector and AISG controlling to WMHC. Remote antenna tilt users saves RET bias-t and installing time. RF-performance and outlook will remain same as WMHC.
