Our history

roWaves Technologies was founded in 2014 by Andrei Avirvarei-YO6TJJ, with a clear goal of helping and providing the amateur-radio community with quality products, RF materials and RF electronic components, available in a single place: www.rowaves.com. roWaves Technologies ™ designs and manufactures in Sibiu, Romania, various equipment for radio-amateurs and electronic hobbysts: low/medium power RF amplifiers (e.g. JUMA PA-100D etc.), SDR transceivers (e.g. mcHF M∅NKA), DDS based HF receivers (e.g. JUMA RX-1), accessories for transceivers, coaxial cables, RF electronic components (iron powder & ferrite toroids, variable coils & IF transformers, RF transistors, quartz crystals & various ceramic filters, RF connectors & adapters, RF integrated circuits, THT trimmer capacitors or silver-mica capacitors etc). Free resources and quality information is available on our website also. Please check it by yourself.

the beginnings of roWaves Technologies

RFD HF & Microwave is set up as a product-logo for 2 first products: a HF-VHF amplifier named TWTA-1-120 and another one, a LNA, named BGA 50-1000. A small test-stand is designed and built.

first commercial product

Introducing a prescaler / divider into our small portfolio: PMC-12080-1000, with multiple divide ratio with operating frequency range up to 1.65GHz.

infrastructure & expansion

In 2015 we built a proper test bench in the lab, on which we are doing all the tests and verifications even nowadays. It is equipped with two working stations. More measurment & testing equipment was also built or purchased during 2014-2017.

a new identity

RFD HF & Microwaves becomes roWaves Technologies ™, in 2016, because we decided to make all the products available first for the Romanian market, especially for the YO Radio-Amateurs.

new products

roWaves Technologies introduces the roW7358-7 SSB 40m receiver and the roWKeySwitch (a navigation keyboard), as well as other RF products. The new launched website is optimized for e-commerce (www.rowtech.ro) and RF engineering services are introduced in our portfolio.

electromagnetic field measurement services

roWaves Technologies starts to offer, at the beginning of 2019, engineering services consisting in performing broadband measurements of the electromagnetic field, for the 30Hz-300Hz, 50MHz-3.5GHz freq. ranges. We also produced the DSB 80m, 2.5W, ROW-W3690 transceiver (v.1 & v.2).

good development

In 2020 we started to manufacture (avialable as kit and finished assembled product) of the mcHF SDR transceiver designed by M∅NKA. We also manufactured the 25W dummy load, DL-25W, a quartz crystal tester (CTROW-130), 3D printed housings, ground-plane antennas or dipoles, for 80 & 20m. We also manufactured coaxial cables assemblies and we established our main product portfolio for amateur radio market.

roWaves Technologies is gaining notoriety on ham-radio market

In 2020 and 2021 we continued to manufacture the M∅NKA mcHF SDR transceiver, we started a collaboration with Finnish Radio team JUMA®RADIO, with legal rights to manufacture various JUMA products: the direct conversion receiver (JUMA RX-1) or the linear power amplifier, with digital control, 100W, PA-100D. We brought & manufactured accessories for transceivers (USB-C power supplies for mcHF / FT-817 / KX-2/3) and we brought into stock electronic components for radio amateurs: iron powder & ferrite toroids from Fair-Rite™ / Micrometals™, RF transistors, variable coils, F.I. transf. 455KHz / 10.7MHz, ceramic filters / resonators / quartz crystals, RF connectors & adapters, RF integrated circuits for RF applications.
