Merry Christmas and Happy New Year!

From all of us at Fat Mongoose Technologies, Happy Holidays, Merry Christmas and a Happy New Year!

Digital Software Radio

We are selling a digital software radio with one or two channels streaming up to 312 MB/s to a disk and data accessible on the web.  Please contact us for more details or check back on this blog soon.


We have single axis or three axis accelerometers, including a rechargeable battery and electronics to power the MEMS sensor. The accelerometers come in sturdy cases with BNC outputs for each axis. You can mount the entire accelerometer unit on large articles under test or you can remove the sensor to measure smaller devices, with a wire tethering the sensor to the electronics. Contact us for pricing, specifications and delivery times.

Battery-powered RF Power Meter

We sell battery-powered RF power meters in sturdy cases with easy-to-read displays.  Battery is rechargeable, ideal for field work.  Contact us for specs, price and delivery details.

Delay Lines

Need delay lines?  Our delay lines feature multiple ports and delays, available in custom lengths.  Nominal delay is 100 ns.  Great for calibration, geolocation system development and antenna array projects.

Solid State HF Transmitters

Solid state HF transmitters available for sale.  Nominal frequency is 4 MHz, output power is 2 Watts.  We can customize the frequency and output power to your specifications.  We can also provide a tunable module.  Available as a circuit board assembly or packaged. Please contact us for pricing and details.

Interested in RF amplification?

FMT has designed and built solid state wideband RF power amplifier stages designed to work below 10 MHz.  This cascadable Class C design outputs two watts per module.  We can power combine many modules to deliver more power.  Available as a circuit board assembly or packaged. Please contact us for pricing and details.


“We have also built tagging and tracking systems using inexpensive commercial tags and customized software for iPhone and Android phones. We work closely with retired NYPD detectives and US Navy veterans on developing concepts of operation for the tags.  An example application is to improve location time for tracking lost children in city parks.  If you have a radiolocation problem requiring a fast, inexpensive solution please contact us.”

Wideband receivers

In addition to transmitters, we offer you wideband receivers.  One of our receiver models is a wideband analog downconverter that you can use to capture data from three different ISM bands.  We include a removable low pass filter so that your output can be either wideband or narrowband.  Both outputs are suitable for digital recording using inexpensive digital oscilloscopes now on the market. Our wideband downconverter includes a rechargeable battery and is built in a rugged metallic enclosure so that you can record signals in the field using a laptop, a digital oscilloscope and our receiver.  These downconverters are available now.  Please contact us for pricing and specifications or stay tuned to our blog.
