FCF500

fci_block_diagrams_no2_fc500.svg

FCF500 is primarily designed for a TDD-mode RF front-end operated in the 800/900MHz frequency bands. FCF500 integrates a linear PA, LNA, Transmit and Receive switching circuitry and associated matching networks all in a CMOS single-chip device.

FCF500 provides superior output power, high power efficiency at Tx part and low noise figure , small current consumption at Rx part . FCF500 can used for multiple applications in the sub-GHz bands from 850 to 950MHz.

FCF500 is manufactured with a CMOS process, and is packaged in a lead-free small package, named 3.0mm x 3.0mm QFN and this chipset requires minimal external components including the power supply bypass capacitors.
