4DSP Inc. has publicly released the AD350, a new PMC product that was successfully engineered to reduce development time of waveforms used in Software Defined Radio (SDR) applications of the Joint Tactical Radio System (JTRS).

The AD350 developed for the processing of waveforms has enabled the JTRS platform to reach into space:

The AD350 Enabling emulation of the GMR EDM modem FPGA Processing Element with the JSR (JTRS Surrogate Radio) deployed by SPAWAR NED & T&E for WNW performance testing.
Provided a target for porting the JTRS GMR MHAL (Modem Hardware Abstraction Layer) enabling porting of GMR waveform PHY components to the JTRS Surrogate Radio (JSR).
Enabled the porting the JTRS WNW of PIM-DM SiS (Signal-in-space) as part of an successful port of the WNW to the JSR.

Features:

Featuring two Altera Cyclone® III FPGAs, the AD350 is a PMC expansion card developed for use in wireless base stations and MIMO test-bed systems applications. The AD350 is the ideal prototyping system to implement flexible and scalable multi-input and multi-output antenna transmitter systems. The AD350 can also be used in synchrotron systems to regulate amplitude voltages, phase.

Mechanically and electrically compliant to the PMC IEEE P1386.1 specifications, the AD350 features Dual-Channel 14-Bit A/D input, sampling up to 150MSPS with a dual-channel 16-Bit 500Msps high-speed D/A output converter supported by 1 external clock source connection and an on-board generated clock signal.

All channels are connected front panel connected via SMA 50Ω terminated double baluns connectors. Input analog signals are AC coupled with wideband transformers operating very efficiently in the 4.5MHz to 650MHz band-range, providing reduced amplitude and phase noise distortion of signals. The output analog channels are also AC coupled, using wideband transformers (4.5MHz to 3GHz). An external trigger is available on the front panel via an SMA connection, single-ended and compatible with LVTTL and TTL GPS receivers generating a 1pps. The architecture provides high performance as well as flexibility with user-selectable external or on-board clock, carefully designed, to minimize jitter and phase noise degradation of the A/D and D/A SNR.
