The ML2730 from RF Micro Devices is a single-chip 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 chip 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. 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 transmitter uses an adjustment-free closed loop modulator, which modulates the on-chip VCO filtered data. The ML2730 includes an up-conversion mixer, a buffer/predriver, and a power amplifier to produce a typical output power of +21 dBm.
