Sub-GHz RF and microwave transceiver for security applications introduced by Microsemi
ALISO VIEJO, Calif., 24 March 2016. Microsemi Corp. in Aliso Viejo, Calif., is introducing the ZL70550 low-power sub-GHz RF and microwave transceiver for security, medical, and industrial applications.
The RF and microwave transceiver combines wireless capability and small footprint for wireless applications operating on coin-cell batteries or energy harvesters, such as electronic shelf labels, retail asset tracking, process control, wearable monitoring, medical diagnostics, and ECG.
Operating in the 779 to 965 MHz unlicensed industrial, scientific and medical (ISM) frequency bands, the ZL70550 consumes 2.8 milliamps while transmitting at -10 decibel-milliwatts (dBm) output power and a similar 2.5 milliamps during reception.
It offers a sleep state current of 10 nanoamperes for low-duty cycle applications. The ZL70550 operates between 1.7 volts to 3.6 volts, and offers variable output power and data rates to 200 kilobits per second.
For applications that require extended wireless range, the transmitter output power, receiver input sensitivity, and data rate can be adjusted to give a link budget to -107 dBm while minimally increasing the power consumption of the device.
The ZL70550 is integrated and offered in a small 3-by-2-millimeter chip scale package. The device includes an advanced media access controller (MAC) that performs most link support functions, received signal strength indications (RSSI), clear channel assessment, Sniff, preamble, and synchronization, packetization, whitening, and forward error correction (FEC).
The Microsemi optional Z-Star protocol enables rapid product development and offers a star configuration to allow a network to be deployed.
