Radio frequency is not only about communication. In medicine and industry, RF is a tool that heats, images and seals. MRI scanners use RF to excite and receive nuclear signals; ablation catheters use RF to treat tissue; factories use RF for induction heating and dielectric sealing. In all of these, the RF chain must be controllable, clean and, above all, reliable.
Medical RF: imaging and therapy
An MRI system's transmit and receive coils are precision RF instruments, and the receive path needs low-noise amplifiers that do not add noise to a faint signal. Therapeutic RF — ablation and diathermy — instead needs a stable, well-characterised power amplifier delivering controlled energy to a precise spot. We stock low-noise and gain-block amplifiers such as the TQP3M9019, the SGA-6389Z, the ERA-1SM+ and the GALI-21+, and transmit/driver amplifiers such as the RFPA3800TR13 and the SBB-3089Z.
Industrial RF: heating without contact
Induction heating, plasma generation and dielectric sealing all drive an RF source into a load, and the amplifier plus its matching and filtering decide efficiency and control. Switches route and protect the chain; we supply parts such as the QPC6044TR13 and the SKY13575-639LF. Filters shape and clean the waveform — we stock the LFCN-3800+ low-pass and HFCN-5500+ high-pass families — and the PE4302-52 step attenuator with fixed pads like the ATN3580-02 handle level control.
Why traceability matters here
When RF drives a medical or industrial process, a mystery part is not an option. We focus on traceable sourcing, date-code and lot consistency, and inspection options (visual, X-ray, decapsulation, electrical test) so the parts feeding a safety-relevant system can be accounted for.

Frequently asked questions
Where is RF used in medical and industrial equipment?
In medicine, RF powers MRI transmit/receive coils, RF ablation that heats tissue to treat arrhythmias and tumours, and diathermy. In industry, RF drives induction heating, plasma generation and dielectric sealing. All need clean, controllable RF amplification, switching and filtering, often with safety-rated isolation.
Why does RF ablation need precise amplification?
Ablation devices must deliver controlled RF energy to a precise location without overheating surrounding tissue. That means the power amplifier and its control loop must be stable and well characterised, with good filtering to keep the delivered waveform clean. Reliability is safety-critical.
What RF parts support these systems?
They use power and driver amplifiers for the RF source, low-noise amplifiers for any monitoring or imaging receive path, switches for routing and protection, filters to shape and clean the waveform, and attenuators for level control. The emphasis is on traceability and consistency.
Can you supply RF parts for medical and industrial designs?
Yes. We stock power and driver amplifiers, low-noise amplifiers, RF switches, filters and step attenuators commonly referenced in medical and industrial RF systems, from traceable sources with date-code verification and inspection options.
