High power radio modem features Category 1 receiver

Tuesday, February 6th, 2018

Radiometrix has launched a high power narrowband radio modem that provides an RF output of up to 500 mW with a data rate of up to 19200 bps. The HNM2 meets the ETSI EN 300 220-1 Category 1 specification for high performance receivers where a short range radio device may have inherent implications for the safety of human life.

This makes the multichannel, low power consumption device suitable for use in safety critical wireless applications such as social alarms and healthcare monitoring.

Current consumption is only 280 mA for transmit and 40 mA for receive, from a supply voltage of 6 V to 16 V dc. Providing a direct interface to SPI, USB, RS232 and RS485 serial ports, it measures only 80 mm x 86 mm x 15 mm. Power can be provided via the USB link or an external supply.

Offering point-to-point and point-to-multipoint communication, the frequency programmable HNM2 has a store and forward repeater mode using dual addressing to extend its operating range.

Other features include a range test mode, a SAW front end filter, 12.5 kHz / 25 kHz channel spacing, data whitening using a pseudo-random sequence, and a digital received signal strength indicator.

The modem can be specified to operate on the licence exempt bands of 458 MHz in UK or 169 MHz and 869 MHz in the EU. Custom frequency bands are also available from 160 MHz to 915 MHz. Channel selection is made by means of a rotary hex switch or using AT commands.

As well as social alarms and healthcare monitoring, the HNM2 is suitable for IoT and other applications, including high end security and fire alarms, lone worker alarms, industrial / commercial telemetry and telecommand, in-building environmental monitoring and control, vehicle data up/download, and automatic meter reading.

PAT-HPA21G Ultra-Wideband Amplifier

Friday, February 10th, 2017

The Lemos PAT-HPA21G is high performance, low noise, ultra-wideband amplifier.
Based on GaN technology, the amplifier achieving high reliability and high efficiency. Most Most power amplifiers are divided into sub bands that cover:

  • 0.1-18GHz
  • 0.5-18Ghz
  • 2-18GHz
  • 6-18GHz

The Lemos Patriot amplifier is quite unique since it has both a relative good N.F but also a quite high output power P1db of 24dbm and high gain of 30db.
This unit can get even better specs if you don’t need the entire freq band of 0.8-21GHZ and only need for example only 6-18GHZ. It also has a  very small form-factor and light weight which makes it suitable for wide range of applications.

Features:

  • GaN Based
  • Ultra-Wideband Operation
  • Compact & Light Weight
  • MIL-STD 810F
  • Low Current 220mA Max.

Applications:

  • Driver Amplifier
  • Low Noise Amplifier in Receiving Chains
  • Radar
  • Ultra-Wideband Measurement Instruments
  • Lab Use
  • Telecomunication
  • Military
  • Medical

PW1-928 RF Data Transceiver Module

Wednesday, February 8th, 2017

The PW1-928 RF transceiver module is designed for reliable bi-directional transfer of digital data over distances of over 300 feet in cluttered urban environments (over half a mile in true line of sight). Operating in the 902 to 928MHz frequency band, the module generates a nominal +7dBm into a 50-ohm load and achieves an outstanding RX sensitivity of –112dBm.

The module uses the industry standard LoRa direct sequence chirp spreading protocol combined with a proprietary data structure to both simplify user implementation and to significantly improve packet transmission reliability. It has a Universal Asynchronous Receiver Transmitter (UART) serial interface that can be directly connected to typical microcontrollers, RS-232 converters or USB adaptors. The module automatically handles all radio functions resulting in a true UART-to-antenna wireless link. Configuration setup is also accessed through the UART interface.

Features

  • True “asynchronous UART to antenna” solution
  • Direct sequence (chirp) spread spectrum
  • 9.6kbps user payload data rate
  • Uses highly robust augmented LoRa protocol
  • Low power standby and TX-from-standby modes
  • Adjustable output power
  • User programmable address and channel-group
  • 3.3-volt logic I/O
  • Digital RSSI (read via serial port)
Applications

  • Direct RS-232/485 wire replacement
  • Asset tracking
  • Automated meter reading
  • Industrial/home automation
  • Wireless sensors
  • Remote data logging
  • Fleet management
  • Traffic and display signs
  • Mass-transit communications
  • Oil and gas sensing
  • Long-range data links
