The SC5312A is a single slot, 3U, PXI Express, 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 SC5505A, and its replica may be used to drive another direct IQ downconverter for coherent reception.

The SC5312A is designed to be paired up with the SC5505A signal source to form a complete RF direct IQ demodulator/downconverter solution. It can also be configured with the SC5412A direct IQ upconverter as a RF signal transceiver.

Whether you are building systems for wireless communication testing, software-defined radio, point-to-point radio, multi-channel coherent systems, or other academic/military programs, the SC5312A’s high dynamic range, low power consumption, and modular/compact size, provide the quality and flexibility you are looking for in your system architecture.

Full implementation instructions, driver software, and example code are provided with each module.
