Radio Connector
Radio connectors are widely used in car, home, and portable radio equipment to ensure high-quality reception of broadcast signals. According to the needs of different application scenarios and equipment, choosing the appropriate connector type (such as F-type, DIN-type, SMB-type, etc.) can ensure the best signal transmission effect.
Radio connector is a specific interface used to connect radio equipment to antennas to ensure effective signal reception. It is mainly used in car radios, home audio, portable radios and other devices. The following are its detailed features, common types and application areas:
1. Product Features
Frequency range: Usually supports frequencies in the range of 0.1 MHz to 1 GHz, used to receive AM and FM broadcast signals.
F-type connector: 0-1 GHz, suitable for TV and radio signals.
DIN-type connector: 0-1 GHz, commonly used in car radios.
Impedance:
75Ω (F-type connector): suitable for home radio equipment and TV broadcasting.
50Ω (DIN-type connector): suitable for car and portable radio equipment.
Insertion loss: In the frequency range below 100 MHz, the typical insertion loss is 0.1 dB-0.3 dB, which ensures the efficiency of signal transmission and reduces signal loss.
Return loss: ≥15 dB, reduces reflection interference during signal transmission and ensures signal quality.
Durability:
Operating temperature range: -40°C to +85°C (vehicle applications), -55°C to +125°C (industrial and communication applications).
Plug life: 500 to 1000 times, ensuring stable contact during long-term use.
Anti-interference design: In order to avoid electromagnetic interference, radio connectors are usually equipped with a shielding layer, especially in vehicle-mounted and high-frequency applications.
2. Common types
F-type connector:
Applied to home audio and TV antenna systems, widely used to receive radio and TV signals.
DIN-type connector:
Standard interface for car radio systems, widely used in car audio equipment in Europe and Asia.
ISO connector:
Standardized interface for car entertainment systems, facilitating compatibility between devices of different brands.
SMB connector:
Miniature, high-frequency connector, suitable for portable radio equipment and high-frequency broadcasting equipment, with a frequency range of up to DC-4 GHz.
3. Application areas
Car radio:
The car antenna is connected to the radio via a DIN-type or ISO connector to ensure that clear AM/FM radio signals can be received in the car. High-performance shielding design prevents vehicle electromagnetic interference and provides a better radio experience.
Home audio system:
F-type connectors are used in home audio and TV equipment to ensure clear transmission of broadcast signals and cable TV signals. Commonly used in FM radio and cable TV receiving equipment.
Portable radio:
SMB connectors or 3.5mm plugs are often used in small portable radio equipment to support external antenna connection and improve signal reception.
Outdoor and marine broadcasting equipment:
Waterproof connectors (such as IP67-rated F-type connectors) are suitable for outdoor or marine use, and can withstand moisture and harsh environments while ensuring stable broadcast signal reception.
