FORT WORTH, Texas--(BUSINESS WIRE)--June 7, 2004

Responding to the fast-growing demand for low-rate wireless connectivity solutions, Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, today announced three new RF (radio frequency) ICs that offer a complete, low-power radio system solution on a single chip, which simplifies the design and reduces bill of material cost for customers. The new transceiver ICs and transmitter IC complement Analog Devices' existing family of ISM (industrial, scientific, and medical) band transmitters (ADF7010, ADF7011) for low-rate wireless connectivity applications. These new RF ICs will be displayed in the Analog Devices' booth #847.

The ADF7012 is a (VHF/UHF) transmitter IC with 50 MHz to 1 GHz frequency operation allowing multiple frequency plans to be implemented for transmit applications such as RF remote controls, remote keyless entry and wireless sensor applications. The ADF7020 & ADF7025 are ISM band transceiver ICs, which operate at bands from 433 to 928 MHz, implement complete transceiver solutions with few external components and are suited to wireless video & audio for alarm, sensor, and security systems, automatic meter reading, and remote transducer applications.

"Analog Devices has once again drawn upon its RF integration expertise to build these single chip solutions that make creating wireless links very affordable," said Christian Kermarrec, vice president, RF and wireless systems, Analog Devices, Inc.

About the ADF7012

The ADF7012 is a single-chip, low-power UHF transmitter with 50 MHz to 1 GHz frequency operation and a Fractional-N PLL (phased locked loop) at the core. It operates at 2.3 to 3.3 volts with very low current consumption. An onboard voltage regulator provides stable performance. The output power is programmable in steps of -16 dBm to 14 dBm, with 0.4 dB steps. Data rates supported are up to 150 kilobits per second (kbits/s). Current consumption is 10 mA at 315 MHz (0 dBm).

About the ADF7020

The ADF7020 is a low power, low-IF transceiver operating in frequency bands from 433 to 464 MHz and 868 to 928 MHz. Data rates supported are 0.3 to 200 kbits/s, FSK (frequency shift keying) of 0.3 to 64 kbits/s, and ASK(amplitude shift keying). It operates on a 2.3 V to 3.6 V power supply with programmable output power from -16 to 13 dBm in 0.3 dBm steps. Its receiver sensitivity is -117.5dBm at 1 kbits/s FSK, -110.5 dBm at 9.6 kbits/s FSK, and -106.5 dBm at 9.6 kbits/s ASK. Current consumption is 19 mA in receive mode and 22 mA in transmit mode ( 10 dBm output). Other features include on-chip VCO (voltage controlled oscillator), Fractional-N PLL, on-chip 7-bit analog-to-digital converter, digital received signal strength indication (RSSI), temperature sensor and a /-1 ppm RF output frequency accuracy made possible by its low-cost 100ppm crystal. Its leakage current is less than 1uA in power down mode.

About the ADF7025

The ADF7025 is a low power, zero-IF RF transceiver operating in frequency bands of 433 MHz to 464 MHz and 862 MHz to 928 MHz. The ADF7025 is a highly integrated FSK/GFSK (Gaussian frequency shift keying) transceiver designed for compliance with FCC 15.247 specifications. A complete time division duplex (TDD) or full duplex RF link can be built with a small number of external components making the ADF7025 very suitable for price- and area-sensitive applications. Combined with the ADF7012 and ADF4106 a complete RF front-end for hybrid 5.8/0.9 GHz digital cordless phones can be implemented.

Pricing and Availability

The ADF7012 is sampling now and will be available in production quantities in July 2004. It is offered in 24-lead TSSOP (thin shrink small outline packaging) and is priced at $1.50 per unit in quantities of 10,000. The ADF7020 is currently sampling and will be available in production quantities in the fourth quarter of 2004. It is offered in 48-pin LFCSP (lead frame chip scale packaging) and is priced at $3.99 per unit in quantities of 10,000. The ADF7025 is currently sampling and will be available in production quantities in the third quarter of 2004. It is also offered in 48-pin LFCSP and is priced at $3.99 per unit in quantities of 10,000.
