详细描述
The ML2730 is a single chip fully integrated Frequency Shift Keyed (FSK) transceiver with fully integrated PA. It is developed for a variety of applications operating in the 2.400 GHz to 2.485 GHz unlicensed ISM band. The ML2730 is mode selectable for operation with digital cordless phones (DSSS or DECT) and higher data rate streaming applications like wireless audio and video.
The ML2730 contains a dual-conversion, low-IF receiver with all channel selectivity on chip. IF filtering, IF gain, and demodulation are performed on-chip, eliminating the need for any external IF filters or production tuning. A post detection filter and a data slicer are integrated to complete the receiver.
The ML2730 transmitter uses an adjustment-free closed loop modulator, which modulates the on-chip VCO filtered data. The ML2730 includes an upconversion mixer, a buffer/predriver, and a power amplifier to produce a typical output power of +21 dBm. A fully integrated fractional synthesizer is used in both receive and transmit modes. Power supply regulation is included in the ML2730, providing circuit isolation and consistent performance over supply voltages between 2.8 V and 3.6 V.
