ML2712-1 Datasheet PDF - Micro Linear Corporation

The 2.4GHz radio chipset is targeted at the IEEE802.11 Frequency Hopping Spread Spectrum standard. Two devices; ML2712 2.4GHz RF Transceiver and the ML2713 IF Transceiver implement a very highly integrated, easy to use radio with a low cost bill of materials. The transmit path includes a DAC and IF up converter in the ML2713 followed by an integrated transmit PLL, 2.4GHz mixer and directly modulated VCO in the ML2712. The result is accurate digital generation of the modulated signal for 802.11 compatibility and maintenance of adequate transmitter range even without RF bandpass filters. The dual conversion receiver features high dynamic range and support for the 4G FSK/2Mbps requirement of 802.11 standard. The chipset also inplements a self aligning descriminator adjusted with every frequency hop.
An optional ML2731 PA Bias Controller completes the set.
