26.5 GHz RF Downconverters

The SC5318A is a C to K broadband single-stage downconverter, converting frequencies from 6 GHz to 26.5 GHz down to 50 MHz to 3 GHz. The LO frequency range is from 6 to 26.5 GHz with an input LO range from 6 to 14 GHz. An internal frequency doubler multiplies the input LO range up to 26.5 GHz. This module also features an internal 26.5 GHz synthesized LO, RF preamplifer, and variable gain control making it a compact standalone downconverter module. With the option for an external LO signal, the SC5318A may be configured for SISO applications or paired together for MIMO applications such as ground-based satellite communications, point-to-point radio, and test instrument systems.

The SC5318A can be combined with SignalCore's SC5308A to form a broadband 100 kHz to 26.5 GHz downconverter. These high-performance converter modules are compact, rugged, and built for simple integration into larger systems.

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