Product Description
The RF2475 includes two downconverting mixers and associated LNAs. It is designed for IS136 handset applications in the cellular 800MHz and PCS 1900MHz bands. Each LNA has a gain bypass mode, which is controlled by the gain select pin. The device internally ties the two mixer outputs together, providing interface to a single IF SAW filter. A frequency doubler is provided to supply the LO signal to the PCS mixer and feeds the PCS transmit LO output buffer. A cellular LO output buffer is also included. The device is fabricated using Gallium Arsenide HBT technology and is packaged in a 28-pin, 5mmx5mm leadless package.
