YIG Tuned Bandpass Tracking Filters
 |
|---|
■ Characteristics
Broad frequency coverage;
Linear continuouis tracking of main channel and tracking channel;
Excellent tuning linearity;
High sideband rejection;
Wide operating temperature range;
Digital or analog continious tuning control;
Universal SMA input and output interface
■ Application
Used in microwave measuring instruments, broadband radar receivers and Electric War systems.
■ Description
YIG-tuned bandpass tracking filters cover frequency ranges of 1 to 2GHz, 0.8 to 2.2 GHz, 1.8 to 4GHz, 2
to 4 GHz, 4 to 8 GHz, 8 to 12 GHz and 8 to 18 GHz, etc. Contemporary selective pass of two ways
combined with self tracking circuit providing unitary tuning with electrically tuned signal
sources(VCO,YTO). All theYIG-tuned tracking filters can be offered both indenpendently and combining
with special analor or digital drivers.
