The RFNM Daughterboard Interface

The RFNM Daughterboard Interface
2x Hirose 100-Pin connectors bringing 4x ADC and 2x DAC traces to every daughter board, plus devoted I2C, SPI, UART, CAN, GPIOs and our customized timing interface.
We’re calling it the RFNM Interface. Click here for a pinout.

Person Interface Connector

Person Interface Connector
Join your exterior System Beneath Take a look at utilizing easy 3.3V, 2.54″ pin headers. Discuss 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 facility of the i.MX processor for standalone purposes, corresponding to a transportable spectrum analyzer with HDMI output and USB keyboard, or join by the USB-C port to a number pc. Want distant operation? The ethernet port and auxiliary energy enter have your again.

Reference Clock In/Out

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

OCXO Possibility

OCXO Possibility
RFNM’s frequency reference may be tuned to at least one ppb accuracy by listening to a close-by cell tower. Nonetheless, for those who nonetheless require an OCXO, a well-designed, hand-solderable footprint is there for you.

Because of the unbelievable silicon within the motherboard and the RFNM Interface, a variety of purposes may be carried out with daughterboards.

Granita

Granita
Granita is our try at constructing probably the most superior RF board of any consumer-grade SDR. We spared no expense, and it exhibits.

The primary RFIC is the Granita from Arctic Semiconductor, which is natively able to tuning from 600 to 7200 MHz. Our board extends this frequency vary all the way down to 10 MHz with the addition of a RFFC2071A mixer.
There are two embedded antennas to make sure that we are able to all the time appropriate any inside frequency drift by synching to the cell community. A posh collection of latches and shift registers plus six totally different timing domains ensures that we are able to all the time change to the wished sign path on the actual time.

We went the additional mile with the addition of 13 preselection filters and 6 totally different LNAs for every frontend, programmable attenuators for each 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 model of the Granita board above. There isn’t any additional mixer, so the frequency of operation is restricted from 600 to 7200 MHz. There are not any embedded antennas, fewer filters and amplifiers.

Lime [under development]

Lime [under development]
We’re working intently with LimeMicro, the makers of the LMS7002 chip and producers of the LimeSDR, to develop a RFNM board utilizing their silicon. It is going to cowl 10 to 3500 MHz.

RTL [concept stage]

RTL [concept stage]
The cheap TV tuners discovered on RTL-SDR gadgets can go as much as 2 GHz, with the limitation of getting a really low actual time bandwidth of about 10 MHz. Nonetheless, every RFNM Interface has 4x 153 MSPS ADC lanes, so how about making it up in amount?

Oscilloscope [concept stage]

Oscilloscope [concept stage]
By designing a easy oscilloscope frontend board, we are able to flip RFNM right into a 4-channel, 50 MHz (3x oversampling) USB oscilloscope. When paired with a RF board, it turns into a mixed-signal analyzer.

Some elements have a protracted lead time (36 weeks), which we now have mitigated by shopping for sufficient of them for a primary batch and organising this waitlist. By putting a preorder and financially supporting the undertaking you’ll assist set up a functioning provide chain and obtain one of many first models off the meeting line.

We’ll e mail you a personalized preorder hyperlink when prepared, plus some occasional product updates.
