UltraSite BTS Units


UltraSite BTS Diagram


Dual Variable Gain Duplex Filter DVxx

Combines transmitted and received signals into one antenna

Amplifies received signals with a variable-gain Low Noise Amplifier (LNA)

Maximun Insertion loss: 1.2 dB


Power supplies PWSx


Receiver multicoupler MxxA

The multicoupler units split Received (RX) and Diversity-Received (DRX)

signals and distribute them to the Transceiver (TSxx) units.


Transceiver unit TSxxThe TSxx unit performs RF modulation/demodulation and amplification for one RF carrier.

The TSxx handles uplink signals from the Mobile Station (MS) to the BTS and downlink signals from the BTS to the MS.

Output power over 47 dBm


Wideband combiner unit WCxA

The WCxA unit(s) can combine transmit (TX) signals from two or four Transceiver (TSxx) units; then feeds the combined signal to the antenna through the TX port of the Dual Variable Gain Duplex Filter (DVxx) unit.

Maximun insertion loss: 3.5 dB
