Customer FAQ
Q1: Does this module support continuous wave (CW) and pulse modes?
A: Supported. The module defaults to CW mode and can switch to pulse mode via an external control signal, making it ideal for dynamic applications such as radar and electronic warfare.
Q2: Is the N-female connector compatible with standard SMA adapters?
Not directly compatible. N-type connectors have an impedance of 50Ω and are physically larger than SMA; a dedicated N-to-SMA adapter is required.AdapterWe recommend using the original manufacturer's cable to ensure
Signal integrity.
Q3: Does the module require an external heatsink?
A: Recommended. Although the built-in aluminum casing provides passive heat dissipation, we recommend addingCooling FanorSerrated Heat SinkImprove heat dissipation efficiency to prevent
Thermal degradation affects output stability.
Q4: Do you offer customized frequency bands or power versions?
Yes. We can adjust the center frequency, bandwidth, or output power to meet your requirements. Minimum order quantity is 10 units with a lead time of approximately 3-4 weeks. Contact our technical team for more details.
