Upper Sadle River, NJ – Pentek has announced its Model 7141 Dual Multiband Transceiver, a VME board-level module targeting SIGINT, software radio and communications applications. The board provides two 125 MHz, 14-bit A/Ds capable of bandwidths of 50 MHz and above. It also provides an FPGA and tools for custom DSP functions.
The Model 7141 is a successor to the Model 7140 PMC/XMC transceiver module. Pentek boosted analog performance in the Model 7141 so that the signal-to-noise ratio and the spurious free dynamic range are improved by 10 dB.
The Model 7141 accepts two full scale analog HF or IF inputs on front-panel MMCX connectors at +10 dBm into 50 ohms with transformer coupling into Linear Technology's LTC2255 14-bit 125 MHz A/D converters. A/D output samples are delivered into a Virtex-II Pro FPGA for signal processing or for routing to other module resources. A TI/Graychip GC4016 quad digital downconverter accepts either four 14-bit inputs or three 16-bit digital inputs from the FPGA. A TI DAC5686 digital upconverter (DUC) and dual D/A accepts baseband real or complex data streams from the FPGA with signal bandwidths up to 40 MHz.
The Model 7141's optional XMC connection complies with the VITA 42 XMC specification and supports high-speed switched-fabric interconnects such as Serial RapidIO and PCI Express. Dual 4X links between the XMC module and the carrier board handle serial-bit rates up to 3.125 GHz. These links operate independently of the PCI interface and achieve streaming data transfer rates of up to 2.5 GB/sec.
The PMC/XMC commercial version of the Model 7141 Dual Multiband Transceiver with FPGA is priced at $10,995 USD, with delivery 8 to10 weeks ARO. The Model 7141 is also available in PCI or 3U and 6U cPCI form factors and ruggedized versions.
