Software Radio PMCs Integrate FPGA Cores

The Model 7141-420 and 7141-430 software-radio PMC modules integrate the company’s GateFlow FPGA IP cores, leaving the end user completely free from any FPGA development tasks. Both are available in conduction-cooled versions to handle rugged applications. The 7141-420 (FPGA installed core with dual wideband DDC and interpolation) promises to extend the bandwidth range of both the digital up converters and digital down converters from very narrow to very wide. For example, the decimation range now extends from two for bandwidths up to 50 MHz to 1,048,576 for audio bandwidths. The 7141-420 best suits general-purpose transceiver functions such as military radio and signal intelligence transceivers. The 7141-430 (FPGA installed core with 256 channels of narrowband DDC) provides a large number of relatively narrowband channels. The module digitizes a 60 MHz bandwidth using either of its two 125-MHz ADCs. The DDC core supports independent tuning of each channel across that bandwidth for down conversion of 256 different frequencies. Each signal is translated to baseband and then low-pass filtered and decimated to a user selectable bandwidth. Decimation is programmable from 1,024 to 9,984. Pricing for the Model 7141-420 begins at $12,995 and the Model 7141-430 starts at $11,995. For more details, contact Mario Schiavone at PENTEK INC., Upper Saddle River, NJ. (201) 818-5900, ext. 770.
