This may be a longshot, but I am searching for a small IC that we could embed in our RFID tags that would have an operating frequency of around 1830 MHz. The size should be as small as 1 millimeter. If you could assist, that would be much appreciated.

Hitachi's µ-chip (pronounced "mu-chip") measures 0.15 millimeter in length by 0.15 millimeter in width and has a thickness of 7.5 micrometers (see Hitachi Unveils Smallest RFID Chip, Hitachi Unveils Integrated RFID Tag and Hitachi Shrinks Smallest RFID Chip). The chip transmits data at 2.45 GHz and has a memory capacity of 128 bits of data, which cannot be overwritten. The read range for the chip, however, is just a few millimeters, because the antenna is right on the chip and is so small that not enough energy can be reflected back to the reader from farther distances.
