ML5805
5.8GHz Variable Data Rate FSK
Transceiver with Integrated PA
Preliminary Data Sheet
GENERAL DESCRIPTION
FEATURES
The ML5805 is a single chip fully integrated Frequency Shift
Keyed (FSK) transceiver developed for a variety of
applications operating in the 5.725GHz to 5.850GHz
unlicensed ISM band. The ML5805 is mode selectable for
operation with digital cordless phones (DSSS or DECT) and
higher data rate streaming applications like wireless audio
and video.
The ML5805 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 ML5805 transmitter uses an adjustment-free closed loop
modulator, which modulates the on-chip VCO with filtered
data. The ML5805 includes an upconversion mixer, a
buffer/predriver, and a power amplifier to produce a typical
output power of +21dBm. A fully integrated fractional
synthesizer is used in both receive and transmit modes.
Power supply regulation is included in the ML5805, providing
circuit isolation and consistent performance over supply
voltages between 2.8V-3.6V.
