The SC5313A is a 400 MHz to 6 GHz direct IQ demodulator, down converting RF directly to analog Inphase and Quadrature IF or IQ baseband. The frequency range of the baseband/IF is from DC to 160 MHz. It can also be operated as a single stage downconverter. The DC coupled differential IQ pair may be fed to any dual channel digitizer for analog to digital data conversion. The local oscillator (LO) is supplied by an external source such as SignalCore SC5506A, and its replica may be used to drive another direct IQ downconverter for coherent reception.

The SC5313A is designed to be paired up with SC5506A signal source to form a complete RF direct IQ demodulator/downconverter solution. It can also be configured with the SC5413A direct IQ upconverter as a RF signal transceiver.

Whether you are building systems for wireless communication testing, software-defined radio research, point-to-point radio, multi-channel coherent systems, or other academic/military programs, the SC5313A’s high dynamic range, low power consumption, and modular/compact size, provide the quality and flexibility you are looking for in your system architecture.

To make integration of our core modules into your system quick and easy, SignalCore offers interface boards that mate directly to our modules. All our interface boards provide pluggable terminal blocks for power connectivity, and are available as USB, RS-232, and SPI as the interface bus. Full implementation instructions, driver software, and example code are provided with each module.
