Pentek Transceiver PMC Modules Feature GateFlow FPGA IP Cores

Pentek’s 7141-420 and 7141-430 transceivers feature GateFlow FPGA IP cores. Because the IP cores are pre-installed, the end user is completely free from any FPGA development tasks. The modules are available in a variety of form factors including PCI, 3U and 6U cPCI, as well as a conduction-cooled PMC version. Linux and VxWorks drivers are available for the 7141-420. Windows drivers are available for the 7141-430 and Linux drivers will be available in the future.

Pentek 7141-420 GateFlow Transceiver Features

  • GateFlow Core 420, two high-performance wideband DDCs and interpolation filter, factory-installed
  • Extended DDC decimation range of 2 to 1,048,576
  • Extended DDC bandwidth range of 40 MHz to 76.3 Hz
  • Extended DUC interpolation range of 2 to 32,768
  • Extended DUC bandwidth range of 40 MHz to 2.44 kHz
  • Conduction-cooled version available, see Model 7141-703

The 7141-420 extends the bandwidth range of both the digital upconverters (DUCs) and digital downconverters (DDCs) from very narrow to very wide. For example, compared to the previous DDC decimation range of 32 to 16,384 without the core, the decimation now extends from 2 (for bandwidths up to 50 MHz) to 1,048,576 (for audio bandwidths). This satisfies an increasing demand to monitor a diverse range of signal classes.

In addition, the range of the DUC has been extended from 2 to 32,768 versus 2 to16 without the core. So now the 7141-420 can handle signals from 40 MHz down to 2.44 kHz, nicely matching the range of the receive signal bandwidths. The 7141-420 is ideal for general-purpose transceiver functions – such as military radio and signal intelligence transceivers ? where engineers need to transmit and receive in a very flexible arrangement of different bandwidths and frequencies for a limited number of channels.

These enhancements to the transmit and receive functions also make the 7141-420 ideal for acquiring, processing and recording radar signals in applications such as linear and 2D phased array beamforming. Because the transmit side is capable of developing analog output signals in the same bandwidth range, it is also serves as a highly flexible radar signal generator for radar system testing, countermeasures and frequency jamming.

Pentek 7141-430 GateFlow Transceiver Features

  • Complete software radio transceiver solution
  • GateFlow Core 430, with 256 Channels of Narrowband Digital Downconverters factory-installed
  • 256 fully programmable NCOs with 32-bit frequency tuning resolution
  • Programmable decimation settings from 1024 to 9984 in steps of 256
  • Conduction-cooled version available, see Model 7141-703

The 7141-430 core provides a huge number of relatively narrowband channels. This is of immense value to customers who need a high-density receiver in an unusually small space. The 7141-430 is far more physically dense than any competitive product currently on the market. For example, two 7141-430 modules support 512 receive channels in a single 6U VME or cPCI slot.

Each module digitizes a 60 MHz bandwidth using either of the two 125 MHz A/Ds. The DDC core supports independent tuning of each channel across that bandwidth for downconversion of up to 256 different frequencies. Each signal is translated to baseband and then lowpass filtered and decimated to user selectable bandwidth. The decimation is programmable from 1024 to 9984, covering many popular communication standards.

The 7141-430 is invaluable in applications such as commercial and military wireless systems with a large number of frequency division multiplexed channels. It is ideal for the receive-side of communication base stations and for signal intelligence surveillance, where the objective is to capture, process and review data in a particular military or commercial frequency band.
