Dual Channel Frequency Extender

DC-30GHz Dual Channel Up & Down Converter
+ VNA Extender Module

EECL are pleased to offer the market a dual channel converter module that can be configured for RF->IF or IF->RF (independent) conversion utilising two frequency and phase locked channels.

Gain control (+30 to -30 dB) of both IF and RF ports is facilitated, and these can be reversed as required independently. Each channel has an extremely high isolation of 90dB.  The LO used for mixing is generated from an extremely low phase noise VCO and can be set anywhere from 8GHz to 30GHz.

The unit has integrated tuneable harmonic filters to prevent unwanted spurious and the unit provides extremely high dynamic range and low noise figure. Unwanted sidebands can be removed as required.

The unit takes a 7V power supply and operates over USB with a simple UART based command set, perfect to control with Matlab, C, Labview. The unit is drift stabilised by the inclusion of an internal oven and therefore suitable for long term use in a calibrated system.
