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).

The architecture of Radio Programming Cable

At present, the software Radio Programming Cable has been paid more and more attention in the civil field. The main reason is that the technical standards of the current communication system are diverse, and the various technical standards and the corresponding systems are difficult to be compatible, and it is difficult to use a unified device to achieve. The radiofrequency part, up/down conversion, filtering and baseband processing of the traditional analog radio system all adopt the analog mode, and the communication system of a certain frequency band and a certain modulation mode corresponds to a special hard structure; while the low-frequency part of the digital radio system adopts digital circuits ( For example, the local oscillator uses a digital frequency synthesizer, source coding and decoding, and modulation and demodulation are completed by a dedicated chip), but its radio frequency and intermediate frequency parts are still inseparable from analog circuits.
