Colorado Electronic Product Design (CEPD) has introduced a digital radio kit consisting of three configurable PCBs.

The Digital Radio Kit (DRK) is intended to aid in the development and test of algorithms and signal processing applications, including digital radio, modem development; software defined radio; high speed DAQ and signal processing; and audio DAQ and signal processing.

The system combines a PCI card, an FPGA signal processing card, and a down converting digital radio card. All three cards have connectors allowing them to stack, forming a digital radio system. The kit will operate in standalone mode or the PCI card can be attached to a computer.

The standard configuration for the digital radio card is the 75MHz to 150MHz band. The digital radio card is capable of transmitting and receiving RF signals. Filters, low noise amplifiers and mixers are socketed to simplify frequency changes. The card includes a frequency synthesizer LO and mixers for up and down conversion for transmitting and receiving.

The card uses a 13bit, 210MSps ADC, a 14bit, 400MSps DAC and an audio codec.

The Colorado Electronic Product Design DRK comes with a user's manual, reference design and example FPGA code.

Pricing starts at $1,600. The device is available now.
