Product Features: 

1, the output with automatic tracking filter, band noise is small, the number of units the same time with help prevent system combinations carrier to noise ratio deteriorates.

2, the use of frequency modulation, double conversion mode surface acoustic wave filter processing, a small band interference; has IF input and output ports.

3, audio frequency, high frequency and radio frequency images are used LO MCU technique, frequency stability and accuracy are high.

4, the push and the whole of the modular functional circuits are used flake technology, machine reliability; LED display channels, available up and down key to set favorite channels.

5, convenience of operation, all of the design level adjustment control on the front panel are the upper and lower keys.

6, the power part of a high dynamic range, high reliability switching power supply; may be customized according to customer requirements of different formats.    Technical parameters  45-870MHz RF output channel within a channel variable
