Innovative Integration has announced the K706 Digital Transceiver. This transceiver supports two antenna inputs and four independent channels of DDC, two channels of DUC, and one spectrum analyzer embedded in a Xilinx Kintex-7 FPGA. It supports monitoring and/or recording of wide or narrow-band spectra or channelized IF band data. The analog front-end is modularized via an FMC site which, fitted with an FMC-1000, employs dual 1 GHz 14-bit ADCs and DACs. This product supports contiguous recording at 160 MByte/s to internal 1.8” SATA drives until running out of disk space.
This rugged, conduction-cooled transceiver is priced at under $30k providing a COTS solution that satisfies even the tightest schedule and budget constraints. The system runs 64-bit Linux or Windows applications and a touch screen is available – ideal for custom wireless surveillance or SDR receiver instrumentation.
Each DDC has its own programmable tuner, programmable low-pass filtering, gain control, and decimation settings, supporting output bandwidth up-to 100 MHz. Data is packetized in VITA-49 format with accurate timestamps, synchronous to an external PPS signal. Each DDC channel can be enabled and disabled on the fly to conserve host computer storage and bandwidth. An embedded power meter monitors the power (dBm) of the ADC inputs, supporting analog gain control of optional, user-supplied external front-end devices.
The spectrum analyzer, which supports windowing, calculates the wide-band spectrum of raw ADC data or the narrow-band spectrum of the DDC output data at a programmable update rate. A programmable peak hold feature may be enabled to latch transient activity in the spectrum. The programmable threshold monitoring spectrum feature tracks spectral activities of up-to 512 bins.
The functionality of the on-board Kintex-7 FPGA may be user-extended. A development kit is available, allowing users to insert custom-made cores to create more advanced applications.
