DESCRIPTION

WE2408 are single-chip FM/FSK transceiver ICs operate in 2.4GHz ISM band. Utilizing a unique direct-conversion, zero-intermediate frequency (zero-IF) receiver architecture, WE2408 provides radio designers a high performance RF transceiver solution with low external component count and small PCB footprint.

The receiver section of the WE2408 provides all of the required receiver functions including local oscillator synthesis (VCO), down-conversion, filtering, automatic gain control (AGC), automatic frequency control (AFC), FM/FSK demodulator and RSSI functions.

The transmitter section contains a directly modulated VCO and RF power amplifier (PA).

Internal, dual, high-performance phase locked loop (PLL) synthesizers/VCOs allow full duplex or halfduplex operation over the entire RF tuning range. Tuning, power management, and gain control (manual) functions are accomplished via serial interface.
