Toshiba RF Chip Wears Many Hats
I have a new article coming soon. It will be an installment of "Build Something RF" and feature the Toshiba TB31262F chip. This is an RF transceiver chip used in many 900 MHz analog cordless telephones but it has many uses far beyond the cordless telephone. I like it because it has full duplex capability (can transmit and receive simultaneously), needs few external active components, and is very flexible.
Its flexibility is the key to its use for the non-telephone applications. It gets this flexibility by having I/O pins for almost every stage of its analog signal processing. Using these is a simple matter of placing the correct passive components between the stages.
