RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Wireless Energy Harvesting System Components & Experimenter Kits
June 25, 2020 - RF Diagnostics, LLC, designs and sells surface mount RF to DC
converters and other building block modules for energy harvesting systems. With
our products you can harvest ambient AC/AM/FM/Wireless Energy to power your IoT
battery-free system. We also provide custom designs for RF/microwave and general
electrical engineering products and design contracting services to clients in the
commercial wireless and defense electronics businesses. We strive to be a high quality
and cost effective design resource for your design team.
RF Energy Harvesting Experimenter Kit RFDKIT−01
RF Energy Harvesting Experimenter Kit is intended for energy harvesting developers
and hobbyists. This energy harvesting design kit is intended for low power system
developers and hobbyists. The kit contains parts to collect and manage the power
from wireless energy from 1 Hz to 6 GHz. Users can connect to the modules
using the included 4-pin headers with a little soldering and clipping. Get started
quickly with your application or research with this kit: Get started quickly with
your application or research with this kit that includes:
• RFD102A RF−DC Converter Module • RFD103A AC−DC Converter Module
• RFD88A Energy Harvesting Engine Module • RFD102A−TB Evaluation
Board for the RFD102A w/ test data at 915 MHz/0 dBm • Please
see details on the RF Diagnostics website.
RF Energy Detector RFD102A-DET
Now you can "see" microwave energy in the 2.4-2.5 GHz range with this fully
assembled and pretested microwave detector. No batteries needed! The microwave power
is harvested and rectified to create a DC voltage that powers the LED. Use this
battery-free detector near your microwave oven or wireless LAN router to detect
if the power level is greater than 1 milliwatt at 2.4-2.5 GHz. The LED
will light up if there is wireless energy and will become brighter if the input
power is increasing. RFD102A-DET is great for high school teachers, technology teacher,
college professors, hobbyists and HAM radio enthusiasts. The antenna can be extended
with alligator clips and longer wires to detect lower frequencies.
RFD199A RF-DC Converter
RFD199A−PCB is a
compact energy harvesting system converts RF/microwave signals to 4.2 V - 5.3 VDC
for mobile phone and other charging applications. Converts 10 MHz to 2.5 GHz
signals to a regulated DC output voltage that may be pulsed in low power conditions
or continuous in high power conditions. The design consists of an RF-DC converter
and a power management system that switches the DC output on when the internal voltage
of the RF−DC converter and storage capacitor reaches 5.3 V. The DC output switches
off when the RF−DC converter voltage and storage capacitor voltage falls below 4.2 V.
When connected to an antenna, the module can extract power from wireless sources
and produce an intermittent or continuous DC output voltage depending upon how much
power is available.
Energy Harvesting Module & System Design
Any of our standard products can be customized for your application. We can support
your application with matching, testing, antenna design, assembly and many other
tasks. Have a new idea for a product? We can help you realize it. We are developing
new products and are always interested in your feedback to guide our product development.
At RF Diagnostics we use Keysight's Advanced Design System for MMIC design and
PCB design. Previous designs completed are quad-band GSM power amplifier modules,
2.4-2.5 GHz/5-6 GHz wireless LAN power amplifiers, broadband power amplifiers,
switch-filter designs, RFID detectors, RF/DC converters and filter designs.
Front End Module Design
We use Keysight's Advanced Design System and Orcad PCB Editor for Front-End Module
designs. Previous design examples are high-volume switch filter modules, dual-band
802.11a/b/g front end modules, 76 GHz car radar module, RFID card design.
RFID Detector System
On an NSF Phase I & II grant to one of our clients, operating as a subcontractor,
the RF Diagnostics design team created a complete RFID MEMS resonator detection
system. Both hardware and software were developed under this contract. The work
was published at an SPIE conference in July 2010.
