LEGACY PRODUCTS

Radiometrix has been manufacturing radio modules for almost 40 years. In that time new designs have improved older ones, and technologies have changed. Some critical parts have even become obsolete. This has produced a family of legacy designs but Radiometrix does not just discontinue products and does not leave users options. Legacy modules can either still be manufactured (with some limitations and caveats) or technical support assistance can be provided to guide users towards more up to date (and often better, and cheaper) equivalents.
Our legacy product range includes the:
TX1, RX1, NRX1, NTX2, NRX2, BiM1 single channel crystal controlled narrowband modules
TX2, RX2, & BiM2 SAW based 433MHz radios. (Both supplanted by modern PLL based designs)
TX2A, RX2A, TX3A, RX3A, BiM2A, BiM3A, BiM2B, HVR2 (all with obsolescent part issues)
BHX2 (458MHz high power, transceiver superseded by SFX2).

LoRa LONG RANGE REMOTE CONTROL/MODEM

Many Radiometrix modules are conventional single frequency radios, transmitting their RF energy in one distinct channel (even multichannel units only use one channel at a time).
The LRM3 is different. It is a transceiver built around the highly innovative Semtech “LoRa” chip-set, which uses a spread-spectrum technique to distribute it's transmitted power over a much wider spectrum. Up to a MHz or more.
This method (in the past limited to high security military radios) gives a LoRa radio exceptional resistance to jamming and interception, and allows it to advantageously use very low data rates to get much longer range (for given transmit power). As an example, 10mW 869MHz LoRa radios can reach out 10km or more.
The LRM3 is an innovative solution for very long range control and low speed data transmission.

COMPACT MODULES

The established ranges of Radiometrix products already put a lot of functionality into very small packages, but advances in RF devices in recent years has noticeably raised the game. Using state of the art RF silicon devices, the MTX2 (400MHz band) and MTX3 (869MHz) transmitters take the high performance narrowband multichannel performance of the LMT series and condense it into an uniquely compact 23 x 12.5mm footprint, with no performance trade-offs at all. These modules are ideally suited to integration into hand held “fob” sized products.

SOCIAL ALARMS

Products in this application area such as pendant alarms for the vulnerable, emergency cord alarms for disabled facilities, are allowed to operate on a specific 869.2125-869.2375MHz allocation, and require the highest (EN300-220 category 1 “life critical”) performance.

Radiometrix offers a range of uniquely suited products, including the COR3 and SAR3 receivers and the LMT3B, the SAT3 (SIL footprint) and MTX3 (sub miniature) transmitters.

NARROWBAND CATEGORY 1 MODEMS

Using the most up-to-date class of fully integrated radio-on-silicon devices, Radiometrix has recently introduced a range of full feature 400MHz (LNM2H and HNM2) and 869MHz band (LNM3 and HNM3) high power (500mW) RS232 compatible radio modems.
This family covers both the simple PCB mounted module type (LNMx) products and more adaptable board level (HNMx) units which provide connectorised RS232 and USB interfaces.

WIDEBAND BiM SERIES - TRANSCEIVERS

In a uniquely small 33x23mm footprint, Radiometrix offers a range of wideband transceivers, supporting the wideband SIL family for applications where bidirectional communications are desired. Again covering both the 433MHz (BiM2C, BiM2G) and 869 or 914MHz (BiM3C and BiM3G), these modules provide a very small yet high performance radio at an attractively low cost.
Where longer range is needed the 500mW BiM3H is the transceiver-equivalent to the TX3FH transmitter.
