Pentek Delivers Highest-Density Software Radio PMC with 256 DDC Channels and Four 200 MHz 16-bit A/Ds

Complete software radio system solution in a single module; Four RF/IF inputs digitized at 200 MSPS with 16-bit resolution; 256 DDC channels independently tunable across four 100 MHz bands;Highly optimized Virtex-5 FPGA technology; Flexible assignment of A/Ds to DDC channels; Extremely low cost per DDC channel.

Upper Saddle River, NJ, May 05, 2008 --( Pentek, Inc., with its proven track record as a pioneer in software radio innovation, today introduced its Model 7151 high-performance, high-resolution software radio module. Four 200 MHz 16-bit A/D converters feed a proprietary FPGA IP core that delivers 256 channels of digital down conversion. Particularly well suited for GSM cell-phone monitoring and signal-intelligence applications, the Model 7151 leads the industry with the best resolution and highest channel density in the market today.

With independent frequency tuning for each of the 256 digital down converters (DDC) channels, the Model 7151 can down-convert any signal within any of the four digitized 100 MHz input bands, significantly enhancing the efficiency and diversity of signal-intelligence applications. Arranged in four banks of 64 DDC channels, each bank can be configured for a unique output signal bandwidth to accommodate applications requiring mixed signal types or multiple modulation schemes. Each DDC bank can be independently sourced from any one of the four A/D converters, which are typically assigned to specific antennas. As a result, the Model 7151 affords the engineer extreme flexibility for simultaneously capturing hundreds of signals spanning a wide range of modulation types, signal bandwidths and antenna sources.

"With its highly optimized 256 channel DDC IP core engine, the Model 7151 represents an entire software radio front end, boasting a channel density eight times higher than any other competing product in the marketplace. The Model 7151 is fully supported with drivers and it comes ready to use with the FPGA code already developed and installed. Not only does the 7151 module reduce development time and risks, it also saves designers space, power and costs in their software radio systems," says Rodger Hosking, vice president, Pentek. "Plus, the flexible decimation settings, input selections and tuning options, all unique to the Model 7151, provide engineers with unprecedented choices to suit specific applications," Hosking added.

A Very Fast Front End
The front end accepts four +10 dBm, full-scale analog RF or IF inputs on front-panel SMC connectors into 50 ohms, with transformer couplings to four 200 MHz, 16-bit A/D converters. The digitized outputs are delivered into a Xilinx Virtex-5 FPGA for routing, formatting and DDC signal-processing operations. The 200 MHz A/Ds accommodate input signal bandwidths of up to 100 MHz, representing a 37% increase over previous Pentek modules.

256 Channel Digital Down Converter
The Model 7151 employs an advanced FPGA-based DDC engine comprised of four identical 64-channel DDC banks. Four independently controllable input multiplexers select one of the four A/Ds as the input source for each DDC bank. In this way, many different configurations can be achieved, including one A/D driving all 256 DDC channels and each of the four A/Ds driving its own DDC bank. Each of the 256 DDCs has an independent 31-bit tuning frequency setting that ranges from DC to ƒs/2, where ƒs is the A/D sampling rate.
