Micrel Rolls Out New RF Receiver with Best Distance Performance on the Market
SAN JOSE, Calif., March 4 -- Micrel Inc., (NASDAQ:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today announced the MICRF211, the Company's newest QwikRadio® RF receiver IC solution. The chip is a 3V, high sensitivity, ASK/OOK receiver for 380 to 450 MHz operation. With its combination of enhanced sensitivity and selectivity, the MICRF211 now leads the industry in distance performance. The device is aimed at meeting the stringent cost and design cycle needs of rapidly growing RF applications including telemetry, wireless sensing, environmental monitoring, consumer entertainment remotes, remote actuation and lighting control, remote keyless entry (RKE) and TPMS. The IC is currently available in volume, with pricing starting at $1.89 for 1,000-piece quantities.
"While the market for RF products has literally exploded in the past few years, two barriers have long persisted," noted John Lee, Micrel's director of Mixed-Signal and RF Products, Micrel. "The manufacturing cost and skill set design expertise normally required to implement RF technology has been prohibitive for many manufacturers. The MICRF211 reinforces Micrel's market position as a global leader in the sub-GHz CMOS RF arena by offering the industry's highest integration, lowest external components, and easiest to use solutions."
The device, with its world class performance, and reliable and easy-to- implement design, is particularly suited for the explosive remote actuation market including garage door openers, security gates, MP3 remote control, remote actuation for lighting, power switches, windows and blinds as well as remote keyless entry, car and security alarms, high-end toys, remote water sprinkler systems, moisture sensors, temperature sensors, TV/Multimedia entertainment systems and tire pressure monitoring systems.
The MICRF211 features high sensitivity, good selectivity (330 KHz, typical, IF BW @ 433.92 MHZ) and image rejection that improves communication distance. The device also offers the highest level of integration with only eight external components required. The IC's IF section is integrated with the image rejection mixer, has an operating voltage range of 3.0V to 3.6V, and a wide operating temperature of -40 to +105 degrees C. Other features include a squelch function for data output noise suppression that minimizes interrupt services request to the MCU and analog RSSI output that provides the receiver systems with the strength of the received signal.
