 |
|---|
■ Characteristics
Broad frequency coverage;
High sideband rejection;
Low inter-channel phase error;
Synchronous linear digital or analog tuning control of three channels;
Wide operating temperature range;
Universal SMA input and output interface
■ Application
Used in microwave measuring instruments, broad band radar recivers and EW systems, amplitude and phase detecting systems ,speed and distance detecting systems
■ Description
Covering frequency 2～18GHz, connecting three channels at the same time，cooperated with the self-tracing circuit，trace tuning with the signal source（VCO、YTO），it composed the breadth phase measuring and the receiving front-end of speed and distance detecting system.
All the products can be offered both indenpendently and combining with special analog.It has analog and digital driving modes.
