Mission

roWaves Technologies was founded in 2014 by Andrei Avîrvarei  (P. Eng. BSc. & MSc., YO6TJJ), with the exact purpose to help the Amateur Radio Community with quality products, materials and electronic components. Since then we have offered quality products and superior customers service to the market. roWaves Technologies ™ manufactures, assembles and designs various equipment for amateur radio market and electronics hobbyists: low/medium/high power RF H.F. to VHF amplifiers (e.g. JUMA PA1000+ HF to 6m Linear Power Amplifier, JUMA PA-100D, 100w+ HF Linear Power Amplifier) and various accessories for ham-radio. We also sell RF electronic components: Magnetic Materials, Fixed & Variable Inductors, RF Transistors, Quartz Crystals & Filters, RF Connectors & Adapters, various Integrated Circuits,  Silver-Mica Capacitors but also D.C. to  HF/VHF/UHF/L/S/C band Fixed Attenuators, Dummy Loads, Step Attenuators, Directional Couplers, Filters, RF Transformers, RF Samplers, for D.C. to microwaves –  laboratory and professional usage.

2013

The beginnings of roWaves

RFD HF & Microwave is set up as a product-logo for the first 2 (two) products: a HF-VHF amplifier (TWTA-1-120) and a LNA (BGA 50-1000). A small test-stand was designed and built.

2014

First commercial product - company registration

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

2015

Infrastructure & expansion

In 2015 we built a proper test bench in the lab, on which we are doing some tests even nowadays. It was equipped with two working stations. More measurement & testing equipment was also built or purchased during 2015-2022.

2016

A new identity

During 2016, RFD HF & Microwaves becomes roWaves Technologies ™, because we had decided at that time to manufacture all available products for the Romanian market, at first, especially for the YO radio-amateurs.

2018

New products

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

2019

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 frequency domains. We also produced the DSB 80m, 2.5W, ROW-W3690 transceiver (v.1 & v.2).

2020

Good development

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

2021

roWaves Technologies is gaining notoriety on the 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: magnetic materials like 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 etc.

2022 - 2023

roWaves Technologies is developping new products and becomes internationally recognised

During the last 2 years we have built and sold various HAM Radio equipment like (tr)uSDX QRP transceivers, KIT or assembled, ultra-portable whip antennas, VLF receivers, various modules for RF constructions, antenna switches and accesories for HAM radio. But we have started to be more focused on a different market. We have introduced the 1kW HF to 6m JUMA PA1000+ amplifier.

2024 - present

roWaves Technologies NCD - New Company Direction

Our company’s new direction started this year with the start of production and manufacturing of PA1000+ 1kW amplifier and its accesories, but alsi other new portable and stationary amplifiers. Our business will be focused mainly on HF/VHF mid to high power (300W/ 600W / 1kW) linear power amplifiers. Among these, we introduced a line of test & measurement accesories for professional lab usage: fixed/step attenuators, instrumentation amplifiers, dummy loads and reference loads, directional couplers and RF samplers, filters etc. Our website will be populated with these products by the end of the year.
