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.
