RECEIVE MODE
In RECEIVE mode, the received signal at 5.8GHz is amplified, filtered, and downconverted to 2.4GHz. The receiver has
two gain modes; High Gain (about 14dB) and Low Gain (about -4dB). Gain mode is set via the state of the RXGN input,
with High Gain Mode corresponding to a logic “1” on RXGN.
TRANSMIT MODE
In TRANSMIT mode, the transmitted signal at 2.4GHz is upconverted, filtered, and amplified at 5.8GHz. The transmit
output power compression point is programmable via an external resistor on the TXISET pin.
