2.4GHz Up/Down Converter
™ The Intersil 2.4GHz PRISM™ chip set
is a highly integrated five-chip solution
for RF modems employing Direct
Sequence Spread Spectrum (DSSS)
signaling. The HFA3624 RF/IF
converter is one of the five chips in the PRISM™ chip set
(see Figure 1 for the typical application circuit).
The HFA3624 Up/Down converter is a monolithic bipolar
device for up/down conversion applications in the 2.4GHz to
2.5GHz range. Manufactured in the Intersil UHF1X process,
the device consists of a low noise amplifier and down
conversion mixer in the receive section and an up conversion
mixer with power preamp in the transmit section. An energy
saving power enable control feature assures isolation
between the receive and transmit circuits for time division
multiplexed systems. The device requires low drive levels from
the local oscillator and is housed in a small outline 28 lead
SSOP package ideally suited for PCMCIA card applications.
