Products Description
Our RF Switch Modules are engineered for high-precision RF signal routing in aerospace, telecommunications, and test & measurement systems. The portfolio includes three industrial-grade solutions - 12-to-1 Switch Module, 16-to-1 Switch Module, and 4-to-1 Switch with Input-Output Isolation. Each module adopts advanced absorptive switch technology to ensure fast switching speed, high isolation, and stable long-term performance.
The 12-to-1 Switch Module supports 4.5GHz–5.5GHz operation with ultra-fast switching time (≤100ns), ≥45dB channel isolation, and 30dBm CW power handling, making it ideal for radar systems and satellite ground stations requiring rapid multi-channel selection.
The 16-to-1 Switch Module operates at 50MHz–90MHz (70±20MHz), offering extremely low in-band ripple (≤±0.25dB), stable IF gain, and minimal group-delay variation, suitable for broadcast systems and precision test benches.
The 4-to-1 Switch (Input-Output Isolation) covers 1GHz–8GHz and delivers exceptional ≥70dB isolation, built-in status monitoring, and both local/remote control, making it a reliable choice for 5G base stations and electronic countermeasure applications.

Products Features
Absorptive Switch Technology
All models adopt absorptive switch designs, which absorb unused channel signals instead of reflecting them. This prevents signal reflection-induced interference, protecting downstream components (e.g., amplifiers, receivers) and ensuring signal integrity in high-density RF systems.
Rapid & Reliable Switching
The 12-to-1 Switch Module achieves ≤100ns switching time, enabling real-time signal routing for time-sensitive applications (e.g.radar target tracking). All modules ensure stable channel selection without signal dropout during switching.
Data Retention & Power Protection
The 16-to-1 and 4-to-1 Switch Modules feature automatic data saving on power-off and parameter restoration on power-up. Critical settings (e.g.network parameters, channel selection) are retained, eliminating reconfiguration time and reducing system downtime.
Flexible Control Modes
The 4-to-1 Switch supports local and remote control, with local control priority (local mode can modify control status, while remote mode cannot)-adapting to both on-site debugging and centralized network management scenarios.
High Signal Integrity
The 16-to-1 Switch Module maintains ≤±0.25dB in-band ripple and minimal group delay variation (≤0.5ns/24h), ensuring consistent signal amplitude and timing-critical for test & measurement and broadcast applications.

FAQ
Q: What is the advantage of absorptive switches over reflective switches in your modules?
A: Absorptive switches absorb unused channel signals (via internal resistors) instead of reflecting them, which prevents signal reflection from interfering with active channels or damaging downstream components. This is critical for high-density systems like satellite ground stations.
Q: Why is the 12-to-1 Switch Module's ≤100ns switching time important for radar applications?
A: Radar systems require real-time target tracking-≤100ns switching ensures rapid selection of different antenna signals, avoiding signal loss or delay that could affect target positioning accuracy.
Q: How does the 4-to-1 Switch's local control priority work in practice?
A: When in local mode, you can modify the control status (switch to remote mode) via the front-panel interface. In remote mode, the remote system cannot change the control status-this prevents accidental remote misconfiguration during on-site debugging.
Q: What does "group delay variation ≤0.5ns/24h" mean for the 16-to-1 Switch Module?
A: It means the time delay of signals passing through the module changes by no more than 0.5ns over 24 hours. This ensures consistent signal timing, which is essential for broadcast and test systems requiring high synchronization.
Q: Can the 4-to-1 Switch handle high-power signals?
A: Yes, it has an input P1dB of ≥5dBm, which is sufficient for most 5G base station and electronic countermeasure scenarios. For higher-power needs, we recommend adding an external attenuator before the input.
Q: How do I check the active channel of the 12-to-1 Switch Module without test equipment?
A: The module has LED indicators labeled for each input channel-when a channel is active, its corresponding LED lights up. This allows on-site verification without additional tools.
Q: Will the 16-to-1 Switch Module retain my channel selection if power is lost?
A: Yes, it has automatic data saving on power-off. When power is restored, it will revert to the last selected channel and gain settings, eliminating the need for reconfiguration.
Q: What is the maximum cable length between the switch module and a remote control system?
A: For the 4-to-1 Switch's TCP/IP control (RJ45), we recommend ≤100m using Cat5e/Cat6 Ethernet cables to ensure stable communication. Longer distances may require a network switch or repeater.
Q: Why is input-output isolation ≥70dB important for the 4-to-1 Switch?
A: High isolation (≥70dB) prevents signals from one input channel leaking to the output or other channels, which is critical for 5G base stations and electronic countermeasures to avoid signal interference.
Q: How often should I calibrate the switch modules to maintain performance?
A: We recommend calibration every 12 months (or after significant temperature changes). Calibration can be done using a vector network analyzer, and we provide a detailed calibration guide in the application notes.
