LS201 L-Band RF Switch satellite 2 3 4

Description

LS201 L-Band RF Switch ​
The LS201 1U rack-mounted L-band RF switch is a RF channel switching system designed for satellite signal transmission systems.

​Key Features​

• ​Automatic & Manual Switching: Supports automatic switching with individually configurable threshold levels for each channel, and manual switching to forcibly switch channels. It allows setting working channel level thresholds—when reached, it can automatically switch to another channel or remain in the current channel as configured.
• ​Network & Remote Management: Equipped with unified network management and point-to-point remote control capabilities (remote control terminal sold separately).
• ​Power Redundancy: Optional single/dual power supplies; dual-power mode maximizes system reliability.
• ​Channel Options: Available in single-channel (LS201) or dual-channel (LS201-2) configurations, with comprehensive horizontal/vertical power supply functions.

​Product Specifications​

• ​RF Performance:

• ​Frequency Range: 950MHz~2650MHz.
• ​Flatness: ±0.5dB (950~2150MHz), ±0.75dB (950~2750MHz).
• ​Input Level Range: 60~100dBuV.
• ​Switching Level: User-defined.
• ​Isolation: ≥75dB (950~2000MHz).
  • ​Polarization & Control: Supports horizontal (H)/vertical (V) polarization switching and LNB high-frequency head power on/off control.
  • ​Low Power Design: Low power consumption and heat generation for enhanced stability, complying with environmental requirements.
  • ​Display & Alarm: Front panel features a -20dB RF output test port; includes buzzer alarm and parameter monitoring with reports sent to the network management system.
  • ​Intelligent Configuration: Parameters can be set locally or remotely; supports integration with network management or point-to-point remote control.
  • ​Display Function: Actively shows the current working channel and level values of each channel.

​Operating Modes​

• ​Automatic Switching Mode: Configurable threshold levels for each channel; supports primary/secondary channel setup and optional automatic return to the primary channel when its signal recovers.
• ​Manual Switching Mode: Allows manual selection of the working channel and forced switching to other channels. Settings are stored in non-volatile memory and restored after power-up (except for A-channel signal transmission, other functions are unavailable during power-down).
• ​Fast Switching: Press and hold the corresponding key for 3 seconds to perform rapid channel switching (detailed operation refer to the user manual).
