RF Engineering Services


RF circuitry design and development is our core competence. Waterbeach Electronics has the ability to conduct detailed analysis of circuits, and establish creative new solutions. With over thirty-five years of RF engineering experience, Waterbeach Electronics has established a portfolio of many RF circuits. Most of these cover a frequency range up to 6 GHz, with some up to 26.5 GHz. These are key building blocks within many RF systems. These circuits include:


- Mixers

Discrete implementations of SBM and DBM types using schottky diodes: e.g. BAT15-04W, BAT15-099R and balun structures implemented on single-layer and multi-layer PCBs etc.

Integrated solutions from Analog Devices, Mini-Circuits etc.


- Frequency Multipliers

Doublers based on our mixer and multi-layer balun designs.

Nonlinear transmission line (NLTL) 


- Amplifiers

Small signal wide-band. 


- Filters and Diplexers

Low-pass, high-pass and band-pass types implemented with surface mount inductors and capacitors or micro-strip structures on a PCB etc.

SAW, High-dielectric Resonator etc.


- VCOs

Wide-band or narrow-band, Low phase-noise types using bipolar active device and varactor diodes for tuning. Frequencies to 10 GHz.

- Synthesisers

Implementations using Analog Devices, Texas Instruments or Maxim Integrated parts, with or without integral VCO.

Multi-loop designs with ultra-low phase noise.


- Antennas

PCB implementations for small portable equipment e.g. IoT devices.

Ceramic antennas.
