OVERVIEW:

The BDA-CELLAB/PCSF-33/33-80-AB assembly enhances the coverage area of radio
communications in buildings and RF shielded environments.

The BDA-CELLAB/PCSF-33/33-80-AB has dual RF paths (Forward / Reverse) to
improve coverage in two distinct frequency bands.

The unit features low noise figure and wide dynamic range. It is based on a dual
duplexed path configuration with sharp out of band attenuation allowing improved
isolation between the receiving and transmitting paths.

BLOCK DIAGRAM DESCRIPTION:

Refer to Figure 1 for the following discussion.

The BDA-CELLAB/PCSF-33/33-80-AB Downlink path receives RF signals from the
base station, amplifies the signal and transmits the signal, without changing the
frequency, into a Distributed Antenna System at the direction of the mobiles. The
signal travels over a DAS medium that then dissipates the signal to the Mobile
subscribers. The BDA-CELLAB/PCSF-33/33-80-AB Uplink path receives RF signals at
the Mobile side from the DAS system, then amplifies it, and transmits the amplified
signal (without changing the without changing the frequency) to the base station. This
Dual Band BDA supports two Uplink and two Downlink, CELL AB and PSC Full
occupy distinct dedicated frequency bands.

For CELL AB Band, the frequency allocations are as follows:

Uplink: 824-849 MHz

Downlink: 869-894 MHz

For PCS Full Band, the frequency allocations are as follows:

Uplink: 1850-1910 MHz

Downlink: 1930-1990 MHz

The Quad-duplexer isolates the paths and route each signal to the proper amplifying
channel.

An Automatic Level Control (ALC) allows for output power limiting. A variable step
attenuator gives 0 – 30 dB of attenuation in 2 dB steps. The use of these controls is
covered in the “OPERATION” section, later in this document.
