Programmable Digital Downconverter
The CommLink™ HSP50216 programmable digital downconverter (PDC) for cellular base stations delivers multiple channel processing of high dynamic range cellular protocols. The PDC contains four channels that can support up to four different protocols simultaneously, including IS-136 TDMA, GSM, EDGE, IS-95 CDMA, 3G and legacy protocols such as AMPS, enabling cellular operators to efficiently support multiple transmission protocols within the confines of one base station. The unit features on-board digital automatic gain circuitry, which, when used in conjunction with on-board digital filtering, provides gain to a low level signal while simultaneously attenuating out-of-band interfering signals. A small outline BGA package that reduces required board space is included. Price: $60 (1000).
