Why RVX3303EPB over AD9361?

The AD9361 is one of the most widely deployed RF transceivers in defense electronics, SDR platforms, and communications infrastructure — and one of the most aggressively export-controlled.


The RVX3303EPB matches the AD9361 specification point-for-point: 70MHz–6GHz coverage, identical <200kHz to 56MHz tunable bandwidth, same 2T2R MIMO architecture, and — critically — the same SPI software configuration. This means existing AD9361 firmware and driver stacks work with the RVX3303EPB with minimal or no modification.


Distributed through Radivix Technology Limited in Hong Kong, RVX3303EPB is not subject to US export controls, enabling procurement for customers in the Middle East, CIS region, and other markets experiencing AD9361 supply disruption.

RF Transceiver FAQ

Does RVX3303EPB require firmware changes when replacing AD9361?
The RVX3303EPB uses the same SPI software configuration as the AD9361, enabling in-place substitution. Most designs require no firmware rewrite. Minor initialization differences may apply — a full comparison document is included in the datasheet package.
What is the tunable bandwidth range of RVX3303EPB?
The RVX3303EPB supports programmable channel bandwidth from less than 200kHz up to 56MHz, matching the AD9361 specification exactly. This covers narrowband to wideband SDR applications.
Can RVX3303EPB be used in GNU Radio or USRP-based systems?
Yes. Due to SPI configuration compatibility with AD9361, RVX3303EPB works with AD9361-based SDR frameworks. Driver adaptation notes for libiio and GNU Radio gr-iio are provided in the migration guide available on request.
Is RVX3303EPB available for export to the Middle East and CIS?
Yes. RVX3303EPB is distributed by Radivix Technology Limited in Hong Kong. It is not subject to US EAR or ITAR controls. Shipment to UAE, Saudi Arabia, Israel, Turkey, Kazakhstan, and other markets is supported.
