TRANSCEIVER, UP/DOWN CONVERTER
4.0 – 8.0 GHz
(Datasheet Rev -)
Product Description
This product is a highly configurable 4.0GHz to
8.0GHz frequency converter. It supports
independent upconversion/downconversion or
transceiver applications. It is programmed via a
Windows-based soft front panel or custom
program using the supplied API manual. User
settings are stored in nonvolatile memory and
recalled at power-up, enabling applications in
target systems without a host computer. Two
internal 4.0GHz to 8.0GHz PLOs alleviates the
need for external LO sources. The primary PLO
is capable of sourcing both the upconvter and
downconverter in transceiver applications. The
secondary PLO supports independent
upconverter and downconverter applications
that require different LO frequencies. The
secondary PLO along with internal DACs and
ADCs allows for automated LO nulling across
the entire 4.0GHz to 8.0GHz operating range.
