Highly integrated RF range extender targets 2.4-GHz low-power wireless networks

Dallas, Tex. — Texas Instruments Inc. (TI) has introduced a highly integrated, radio frequency (RF) range extender for 2.4-GHz wireless applications such as ZigBee networks, wireless sensor networks and industrial, consumer and audio equipment. The CC2590 extends range up to eight times the line-of-sight by integrating a power amplifier for improved typical output power of +12 dBm and a low-noise amplifier for improved receiver sensitivity of +6 dB.

In addition to a power amplifier and low-noise amplifier, the CC2590 integrates switches, RF matching, inductors and a balun, which simplifies high-performance designs and enables customers to develop a high output power wireless solution with very few external components.

The CC2590 provides a seamless interface to all of TI's existing and future 2.4-GHz RF transceivers, transmitters and system-on-chip products for improved RF performance, simplified development and reduced time-to-market. The CC2590 also complements the recently introduced CC2591, which extends range up to 15 times line-of-sight with up to +22 dBm output power.

Pricing: Available now in a 4 x 4-mm QFN-16 package, starts at $2.25 in quantities of 1,000 (Suggested resale pricing). The CC2590EMK evaluation module kit is priced at $99.00.
