ISL3856 MAC
See “The ISL3856 Media Access Controller (MAC) Protocol
Handler” section.
BBP ISL3863
The BaseBand Processor uses CCK modulation and a Rake
architecture to reduce the effects of multipath. This reduces
the error rates in typical office environments to improve
overall data throughput.
IF HFA3783
The IF is a linear design with AGC. This permits the use of
equalizers in the BBP. An IF overload detector and
selectable low gain LNA mode work with the BBP to extend
dynamic range without sacrificing sensitivity. The IF LO
frequency is generated by an external VCO. Filtering at the
IF is done by a SAW BandPass filter.
HFA3683 / HFA3983 RF
The RF IC’s are produced in advanced SiGe technology to
realize improvements in integration, performance, and power
consumption. Integral PLLs in both RF and IF parts eliminate
the need for an external synthesizer. The HFA3683’s internal
LNA noise figure is improved so that an external LNA IC is
no longer needed. The chipset is designed so that the parts
can be interfaced with few external components.
The RF LO frequency is generated by an external VCO. The
PA incorporates an integral power detector that is monitored
by the BBP. The BBP controls the IF gain to maintain
constant output levels.
Antenna System
A dual spatial integrated antenna system is used to select
the most optimal signal. The antennas are sleeved dipoles
directly connected to the PCB.
