RFMD ML5805 5.8GHz Variable Data Rate FSK Transceiver Datasheet
The ML5805 is a single-chip fully integrated Frequency Shift Keyed (FSK) transceiver developed for applications operating in the 5.725GHz to 5.850GHz unlicensed ISM band. It is mode selectable for operation with digital cordless phones (DSSS or DECT) and higher data rate streaming applications like wireless audio and video.
The device contains a dual-conversion, low-IF receiver with all channel selectivity on chip, eliminating the need for external IF filters. The transmitter uses an adjustment-free closed loop modulator and includes an upconversion mixer, buffer/predriver, and power amplifier to produce a typical output power of +21dBm. A fully integrated fractional synthesizer is used in both receive and transmit modes. This manual is written in Chinese.
