Microsemi Corporation (Nasdaq: MSCC) has released its low power sub-GHz radio frequency (RF) transceiver for industrial, security and medical applications, the company said.
In addition to its best-in-class low power characteristics, the new ZL70550 combines high performance wireless capability, a high level of integration and an extremely small footprint at competitive pricing. The ZL70550 is well-suited 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 779-965 megahertz (MHz) unlicensed industrial, scientific and medical (ISM) frequency bands, the ZL70550 consumes only 2.8 milliamps (mA) while transmitting at -10 decibel-milliwatts (dBm) output power and a similar 2.5 mA during reception.
The ZL70550 is highly integrated and offered in a very small 3×2 mm chip scale package. Other than the antenna and, in some cases, its matching network, only a crystal, resistor and two coupling capacitors are required.
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 full star configuration to allow a full network to be deployed.
Microsemi offers a portfolio of semiconductor and system solutions for communications, defense & security, aerospace and industrial markets. Microsemi is headquartered in Aliso Viejo, Calif., and has approximately 4,800 employees globally.
