Description

The AT48810 RF module is intended for time domain duplex spread-spectrum communications under FCC Part 15, 902-928 MHz unlicensed operations. This module features RF despreading and narrowband IF for powerful interference rejection. Spreading is via direct sequence. The unit can also be operated in a narrow-band configuration (FCC limits power to 1 mW in narrow band) by restricting the DC voltage to the power amplifier so that the transmit power is less than 0 dBm per FCC regulations. The unit can also be run in slow half duplex or simplex mode.
