Texas Instruments introduced the low-cost, sub-1GHz CC11x1-Q1 device family. The CC11x1-Q1 family includes UHF transmitters, receivers and transceivers. They are designed for very low-power, high-range wireless, and car access systems. The CC11x1-Q1 features a simple RF design, an easy-to-use SPI interface, and does not require external filters or switches which results in a low-cost design. Pricing of the CC11x1-Q1 device family starts at $1.10 for 100k of the CC1151IRHBRG4Q1. These devices are available in a QFN 5x5mm, 32-pin package, resulting in the smallest board space for UHF transceivers on the market.
