6 GHz IQ Modulator

The SC5413A and SC5412A are 400 MHz to 6 GHz direct IQ modulators upconverting analog In-phase and Quadrature IF or IQ baseband directly to RF. Each module can also be operated as a single stage upconverter. The DC coupled differential IQ pair may be driven by any dual channel baseband source such as a dual channel arbitrary waveform generator. The local oscillator (LO) is supplied by an external source (such as the SC5506A or SC5505A respectively), and its replica may be used to drive another direct IQ upconverter for coherent transmission.

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 SC5413A and SC5412A’s high dynamic range, low power consumption, and compact size provide the quality and flexibility you are looking for in your system architecture.

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