6–26 and 24–44 GHz Frequency Converters


Improve your time-to-market with this Richardson RFPD Design Accelerator.

These modules are designed to interface directly with software-defined radios, such as those commonly implemented using Analog Devices’ Mixed-Signal Front-Ends (MxFE evaluation kits available here and here), or similar software defined radio, to obtain a complete mmWave system.

Up to four modules can be combined in parallel to create complex MIMO applications.

About RadioThorium


IF and IQ baseband input/output, TDD and FDD modes, internal and external LO reference.


Control is provided via either SPI or USB interfaces. The interfaces can be cascaded (in series, up to 4 units) to support a single, external controller.


Eliminates the need for multiple controllers and simplifies timing and synchronization between units.

>1 GHz Instantaneous Bandwidth

Instantaneous bandwidths up to 1.6 GHz (4T4R config) and higher.

Drives Phased Arrays

Stacking up to 4 RadioThorium modules is ideal for phased array applications.

Additional RadioThorium Features

The IF ports are designed for the 2 to 6 GHz range. Onboard user selectable filter banks provide 20, 50, 100, 200, 400, 800, 1400 MHz bandwidths along with a bypass path option.

On the low frequency side, both up and down conversion paths support I/Q and IF interfaces. On-board I/Q buffers allow direct connection to external, single-ended ADC/DACs operating at up to 6 GHz. Programmable low pass filters (LPFs) in the buffers help reduce out of band spurious signals.

RadioThorium can be used for either Time Division Duplex (TDD) or Frequency Division Duplex (FDD) systems. The UC and DC paths have a single reference source for synchronization purposes but have separate, high-performance, local oscillators (LOs) for FDD applications. Inputs on each path are also available for injection of external LO and clock sources.

Control of the card is provided via either SPI or USB interfaces. The control interfaces can be cascaded (in series) to support a single, external controller. An API Control Interface Specification is provided with detailed command and timing information. Two control modes are available. The first is a console API based on SCPI/488.2. The second is a 32-bit binary structure, for automated control and timing of critical applications.
