It's really not difficult to talk about the electrical performance of UHF interface!

The UHF interface is one of the RF connectors. It has the same electrical performance as the RF connector. Therefore, as long as you know the electrical performance of the RF connector, you can basically understand the electrical performance of the UHF interface. that UHF What is the electrical performance of the interface? Next, Deso Electronic Industrial Defense Division will focus on the electrical performance of the UHF interface.

The electrical performance of UHF interface mainly involves three aspects: characteristic impedance, frequency and VSWR. The specific contents are as follows:

1. Characteristic impedance of UHF interface

The characteristic impedance of UHF interface is mainly 50 Ω and 75 Ω. Most UHF connectors have both 50 Ω and 75 Ω specifications. Generally, 50 Ω UHF connectors are used on high frequency and high-performance products; 75 Ω UHF connectors are commonly used for products with lower frequency, most of which are below 4GHz, especially for consumer electronic video. Users should select connectors matching their impedance according to their products. If the user uses 75 Ω RG 59 Cable, the 75 Ω connector should be selected.

2. UHF interface frequency

Each UHF interface has a range of frequencies. Users must select the appropriate UHF connector according to the operating frequency of their products. The electrical performance of the whole machine will be affected if the connector with lower working frequency is selected; Or choose expensive high-precision and high-frequency connectors to waste. The use frequency of UHF interfaces produced by different companies is quite different, and the use frequency of low-quality UHF interfaces is not up to the standard at all, so it is important to confirm the electrical performance when choosing UHF interfaces.

3. UHF interface VSWR

VSWR is one of the key indicators of the UHF interface and the measurement standard for measuring the amount of signal returned from the connector. It is a vector unit, including amplitude and phase components. The VSWR of the same type of UHF interface is different in different frequencies. Generally speaking, the higher the frequency of use, the higher the VSWR. If you want to know the VWSR of the UHF interface at a specific frequency, you can ask the UHF manufacturer.

That's all for the electrical performance knowledge of UHF interface. Our industrial protection division will continue to edit, sort out and publish more technical documents related to UHF connector on the UHF technical topic page for your free reference.
