Figure 1: Repeater RF Block Diagram
The block diagram showed in figure 1 illustrates the overall functionality of Dekolink
iDEN Repeater. Dekolink's programmable iDEN Repeaters employ advanced
up/down conversion Intermediate Frequency (IF) Surface Acoustic Waves (SAW)
filtering architecture. This new technology offers distinct advantages over conventional
repeaters, when high adjacent selectivity and spectrum purity is required.
The Channeler Module (blue colored) consists of dual Radio Frequency (RF) Up/Down
Converter sub-modules for Downlink and Uplink paths. The Channeler amplifies the
received RF signals and converts them into an intermediate frequency (IF). The IF
outputs are connected to a SAW Filter. The IF outputs are converted back to the
original RF frequencies.
Cellular modem is an option for remote monitoring and control repeater parameters.
