ML5800
5.8GHz Low-IF 1.5Mbps FSK Transceiver
FINAL Datasheet
GENERAL DESCRIPTION
The ML5800 is a high integration 5.8GHz Frequency
Shift Keyed (FSK) transceiver that integrates all
frequency generation, receive, and transmit functions
required to realize a digital cordless telephone. Only a
power amplifier (PA) and antenna switch are required to
form a complete 5.8GHz digital radio. The ML5800
operates in the 5.725 to 5.850GHz unlicensed ISM
band. It can be used to implement both Direct
Sequence and Frequency Hopping Spread Spectrum
radios.
The ML5800 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 ML5800 transmitter uses an adjustment-free two-
port closed loop modulator, which modulates the on-
chip VCO with filtered data. An upconversion mixer and
buffer/predriver produces output of 0dBm at 5.8GHz. A
fully integrated 3.9GHz fractional synthesizer is used in
both receive and transmit modes. Power supply
regulation is included in the ML5800, providing circuit
isolation and consistent performance over supply
voltages between 2.7V-3.6V.
