Product Description

This model support any single systems of CDMA, EGSM, GSM, DCS, PCS, WCDMA, AWS, LTE.  Please remark the frequency you need.


Work Frequency: CDMA450, LTE700 (A/B/C/D), IDEN800, CDMA800, GSM900 & EGSM, DCS1800, PCS1900, CDMA2000, WCDMA2100, AWS2100, LTE2600 and so on. 

Trunk amplifier is also a special repeater with 20dB gain both link and 20dBm output power in downlink. In some site, we could add one or more trunk amplifiers in one project link to achieve a quite large coverage. Each line amplifier will provide an additional 20dBm power level, enough to cover between 1000~3000 square meters. And if the capacity of donor signals are sufficient, more than 20 trunk amplifiers can be deployed, thus a quite large coverage can be achieved. 

In some special solution, the cable maybe runs too long and it will loss much signal. We could add a trunk amplifier into the main cable line to boost the signals again. 


1. Elegant and compact design.

2. Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

3. Light weight, small volume, simple and convenient installation design.
