RFX PT560-10-GPS OCXO

RFX Group has announced a complete redesign of it’s well established PT560-10-GPS surface mount OCXO range which now features a long term satellite locked temperature stability combined with a 20% reduction in both footprint and height. Operating at 10MHz, the new design offers a GPS locked long term temperature stability of ±0.001 ppb or reverts […]

Lemos International Presents REYAX new LoRa® Antenna Transceiver Module RYLR998

RYLR998, which is newly developed by REYAX Technology, is a transceiver module features the LoRa® long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. RYLR998 uses NUVOTON MCU & Semtech LoRa® high-performance engine and has 868/915MHz frequency range. It supports the UART interface and can be […]

Way Down Low. 27MHz: An Unexpectedly Useful Radio-control Band Allocation

When considering wireless systems, there is an increasing tendency in recent years to think in terms of the highly visible, frequently encountered high UHF to low microwave bands (800MHz to 2.5 or 5.8GHz) where mobile phones and domestic and commercial WiFi and Bluetooth networks are found. Even moving into the industrial low power radio niches […]

VX2M NBFM Vibration Resistant Category 1 Multi-channel Transceiver

VX2M is a 400MHz band transceiver conforming to the Radiometrix TR2M pinout. It uses a sophisticated combination of techniques to produce a very robust device with excellent resistance to vibration. It meets the ETSI Category 1 high performance receiver specification to be used where the operation of a SRD may have inherent safety of human […]

Lemos International Helps University of Michigan Aerospace Students Fly Around the Globe

A University of Michigan Aerospace Engineering senior design team, sponsored by Lemos International and the Michigan Exploration Laboratory (MXL), is currently developing a global high-altitude balloon module they plan to fly around the globe by January 2020 on a homebrew hydrogen balloon. Lemos International has sponsored the module’s communications subsystem by supplying UHX1/SHX1 radios to […]

Now Available: InHand InDTU332 Series

The InHand InDTU332 series industrial-grade wireless data terminal uses cellular network as the bearer network to provide wireless data transmission channel over TCP/IP. It functionally completes wireless data communications between remote control station serial devices and the central control system, to enable remote control of industrial field sites. The InDTU332 series is small in size, […]

Radiometrix VHF Bird Alarm Transmitter

The BAT1 On-Off-Keying (OOK) transmitter is intended for the tracking of small animals such as birds and operates in the 150MHz and 173Mhz bands dependant on country specifics. It is designed to meet ETSI EN 300 220-2 radio standard. Functional description The BAT1 transmitter consists of an OOK modulated crystal Oscillator and frequency multiplier with […]

What can you do with an M48?

Radiometrix has had the M48 radio modem chip (and it’s application boards) for a little while, but I’m not 100% sure that all the interesting tricks it can do are entirely obvious. The M48 is a 4800 baud radio modem, compatible with narrowband radios. That means MURS band units, low power UHF modules and licensed […]

C type control products

The purpose of this document is to discuss the simple, fixed address control devices (CTR, CTA and the CX families) and their supported hardware. Rolling code (K series) units will be covered in a different document. I have updated the document to detail the products which we have designed, built and sold, but never actually […]

Let’s use MURS!

There is a band allocation available in the USA that doesn’t get the attention it deserves. I’m talking about the MURS band. Five narrowband spot frequencies around 151-154MHz (yes: VHF) where up to two watts of transmit power are allowed. For those of you brought up on 2.4GHz, that means “range” with a capital “R”. […]
