MELBOURNE, Fla.-Harris Semiconductor announced earlier this month its new 800 MHz Interim Standard-95A chips for cellular handsets. With these new products, the company now has two chips for Qualcomm Inc.-based cellular applications, together with a dual-mode chipset for DSP Communications. This announcement marks Harris Semiconductor’s first venture into the cellular market.
The chips for Qualcomm applications include the HFA3665 downconverter with automatic gain control-used in the front end of a receiver; and the HFA3667, used as the upconverter.
The chipset for DSPC includes these two chips, plus the HFA3765, which is a fully integrated IF AGC amplifier and quadrature demodulator; and the HFA3767, which comprises an upconverter quadrature mixer with an output gain control stage.
“Harris’ chipset solution offers higher integration over discrete solutions, and provides both RF and IF transceiver functions of a cellular handset while supporting IS-95A standard requirements,” said Chris Henningsen, director-wireless marketing at Harris.
All of the chips and chipsets are offered in low-profile packages to conserve board space, encouraging manufacturers to make their designs more compact, said Harris.
The dual-mode chipset will sell for $14 in volume, with production scheduled for this spring.
