LGP Tower Mounted Ampl ifi er design

LGP´s TMA solutions consist of a wide variety state-of-the-art products designed

to be installed outdoor in towers or in the BTS cabinet. The main design criteria

have been to maximise product reliability, electrical performance and to minimise

size and weight. LGP’s products have a vented design to cope with the hardest of

environmental conditions and temperature changes.

A TMA unit comprises high Q band-pass filters, low noise amplifier (LNA) in a

balanced configuration, current extractor and a LNA bypass circuit. The unique

patented mechanical design has all electronics integrated within the filter body.

This combined with the ventilation system gives the unique field proven LGP reliability.

Lightning protection is implemented on all ports. A micro processor based system

supervises parametres such as current consumption on each RF transistor, input

voltage, VSWR and data communication to the BTS.

Products are available for all systems within the 450-2200 MH z frequency band.

Today’s generation of LGP TMAs are available in gain versions from 12-33 dB and

some with adjustable gain.

LGP state-of-the-art TMAs are designed based on LGP unique system knowledge

including 3GPP specification and co-location with other systems. The invaluable

system knowledge has been achieved from around half a million T MA installations

world wide with billions of hours in field. Feedback from the market together with

the precise work from R&D has resulted in a wide spectrum of TMAs for 3G

networks. Below a small selection can be found.

• Twin TMA where two units are combined into one. You only need one

TMA per sector instead of two.

• TMA with extremely compact design and superior performance within 1.5

litres of volume.

• Current injector with VSWR monitoring of the antenna system.

For maximum reuse of existing 2G infrastructure when building infrastructure for 3G,

LGP also provides low loss high quality co-siting filter products such as Diplexers and

Triplexers. The TMA product line also includes accessories like Duplex filters, Power

Distribution Units (PDUs), Current Injectors (CINs) and Multi pack mounting plates.

LGP offers complete solutions for today’s networks and future networks.

Duplex fi l ter

The LGP Filter product line comprises Duplex Filters for combining receive and

transmit signals to a common port and Diplex Filters for combining 800/900 MH z

and 1800/1900 MH z base stations or 2G and 3G basestations to a common port.

All filters have built-in lightning protection of the BTS and the Power Distribution

Unit. There are models for both indoor- and outdoor installations. For installations

where TMAs are used, filters with DC transparency are available. This product family

supports base stations with built-in TMA power and supervision functionality.

LGP supplies standard and custom designed high performance RF filters for all

frequencies. For other filter types e.g. Triplexers and other co-siting products, pleaserefer to the LGP co-siting brochure.

Power distribution unit (PDU)

LGP PDU Lite provides power to and supervises the status of the LGP Tower

Mounted Amplifiers. PDU Lite enables TMA installations to be carried out on a per

sector basis and supports all common site configurations. The PDU Lite family is

based on a module that supports two TMAs, i.e. one sector with diversity. If the site

comprises two sectors or more, modules are added and daisy chained together. PDU

Lite is available in indoor and outdoor versions and supports wall, pole or 19"rack

mounting. PDU Lite has isolated input and output ports that cater for polarity

independent DC supply. This combined with the compact size and multiple mounting

options, ensures that PDU Lite can be used with the vast majority of base stationequipment.

Cur ren t In jector (CIN )

The LGP TMA family is powered by DC via the feeder cable. In order to inject this DC

voltage to the cable at the base station, LGP has developed a range of Current Injectors

(CIN), also known as Bias Tees. LGP CINs are available for indoor- and outdoor

installations. There are also models with built in VSWR monitoring and alarm function.

A special version with a right angle oriented connector for installation inside base

station cabinets with limited depth behind the doors is available. All LGP CINs have

high performance lightning protection circuits to protect the BTS and the PDU.

Mult i pack m ounting plate

The LGP Multi pack provides a flexible and compact mounting solution for fast and

easy installation of multiple TMAs. The Multi pack is available for mounting two,

three, four or six TMAs in a compact cluster with low visibility. TMA Multi pack

brackets support with wall and pole mount.
