General Description
AD6411 General Description
The AD6411 provides the complete transmit and receive RF signal processing necessary to implement a digital wireless transceiver based on the Digital Enhanced Cordless Telecommunications (DECT) standard. The AD6411's receive signal path consists of a mixer, IF amplifiers and PLL demodulator. The low noise, high intercept mixer is a development of the doubly-balanced Gilbert-Cell type. It has a nominal 16 dBm input-referred 1 dB compression point
and a 8 dBm input referred third-order intercept. The limiter amplifier provides sufficient gain to drive the PLL demodulator, which provides selectable analog or sliced outputs. The RSSI output provides a voltage proportional to the receive signal strength. It measures nearly 100 dB IF signal strength range with 14 mV/dB gain scaling.
The transmit path accepts baseband data, which is filtered and applied to the VCO directly. The VCO operates at half the RF carrier frequency, and is doubled to avoid pulling due to leakage from the output. An on-chip PLL frequency synthesizer provides channel selection. Operating modes are selected either through a serial bus or asynchronous control pins. This allows compatibility with most of the available DECT baseband controller ASICs. The AD6411 is packaged in a 48-lead LQFP.
