All the interfaces you will ever need

The RFNM Daughterboard Interface

The RFNM Daughterboard Interface 2x Hirose 100-Pin connectors bringing 4x ADC and 2x DAC lines to each daughter board, plus dedicated I2C, SPI, UART, CAN, GPIOs and our custom timing interface.
We are calling it the RFNM Interface. Click here for a pinout.

User Interface Connector

User Interface Connector Connect your external Device Under Test using simple 3.3V, 2.54" pin headers. Talk UART or I2C to the onboard processors, use the GPIOs or the programmable, differential clock output.

2x USB 3.0, HDMI 2.0, 1 Gbps Ethernet

2x USB 3.0, HDMI 2.0, 1 Gbps Ethernet Use the power of the i.MX processor for standalone applications, such as a portable spectrum analyzer with HDMI output and USB keyboard, or connect through the USB-C PD port to a host computer. Need remote operation? The ethernet port and auxiliary power input have your back.

Reference Clock In/Out

Reference Clock In/Out Use the Si5510 to generate clocks up to 3.2 GHz, or feed your lab's reference to it.

OCXO Option

OCXO Option RFNM's frequency reference can be tuned to one ppb accuracy by listening to a nearby cell tower. However, if you still require an OCXO, a well-designed, hand-solderable footprint is there for you.

A new ecosystem of compatible boards

Thanks to the incredible silicon in the motherboard and the RFNM Interface, a wide range of applications can be implemented with daughterboards.

Granita

Granita
Granita is our attempt at building the most advanced RF board of any consumer-grade SDR. We spared no expense, and it shows.

The main RFIC is the Granita from Arctic Semiconductor, which is natively capable of tuning from 600 to 7200 MHz. Our board extends this frequency range down to 10 MHz with the addition of a RFFC2071A mixer.
There are two embedded antennas to ensure that we can always correct any internal frequency drift by synching to the cell network. A complex series of latches and shift registers plus six different timing domains ensures that we can always switch to the wanted signal path at the exact time.

We went the extra mile with the addition of 13 preselection filters and six different LNAs for each frontend, programmable attenuators for both receiver and transmitter paths and two transmitter amplifiers. Click here for a block diagram.

Granita Lite [under development]

Granita Lite [under development]
Granita Lite is a simplified version of the Granita board above. There is no extra mixer, so the frequency of operation is limited from 600 to 7200 MHz. There are no embedded antennas, fewer filters and amplifiers.

Lime [under development]

Lime [under development]
We are working closely with LimeMicro, the makers of the LMS7002 chip and manufacturers of the LimeSDR, to develop a RFNM board using their silicon. It will cover 10 to 3500 MHz.

RTL [concept stage]

RTL [concept stage]
The inexpensive TV tuners found on RTL-SDR devices can go up to 2 GHz, with the limitation of having a very low real time bandwidth of about 10 MHz. However, each RFNM Interface has 4x 153 MSPS ADC lanes, so how about making it up in quantity?

Oscilloscope [concept stage]

Oscilloscope [concept stage]
By designing a simple oscilloscope frontend board, we can turn RFNM into a 4-channel, 50 MHz (3x oversampling) USB oscilloscope. When paired with a RF board, it becomes a mixed-signal analyzer.
