Key Technologies of Radio Programming Cable

1. Multi-band down-conversion and broadband RF

For the antenna of the Radio Programming Cable system, it should have a multi-band antenna and a programmable radio frequency conversion function. On the basis of satisfying the antenna gain, physical size and price, it should have a working bandwidth of 2MHz-3MHz. It is not necessary to cover the whole frequency band in the Radio Programming Cable, but only need to cover several windows of different frequency bands. Therefore, a combined multi-band Radio Programming Cable can be used to perform tuning, energy control, and low-noise preamplifier (LNA) for broadband radio frequency. ) configuration is also a key technology, and the optimal design of the system can be carried out with the aid of computer-aided design (CAD).

2. Broadband A/D part.

The key to determine the performance of Radio Programming Cable broadband analog-to-digital conversion is sampling and the number of bits. The sampling rate is determined by the signal bandwidth, while the number of quantization bits requires a certain dynamic range and DSP precision. Because the existing single-chip ADC cannot meet these two requirements, multiple ADCs can be used in parallel.

Through the above introduction and analysis of Radio Programming Cable, hope it helps you.
