SMW L-Band Diplexer 10MHz
- Minimal insertion loss for L-Band signals
- Outdoor suitability with IP67 rating
- Broad operating temperature range
- Combines or separates 10 MHz and L-Band frequencies
- Passive design, eliminating the need for external power
- Available with F-type, N-type, or SMA connectors
The Swedish Microwave Diplexer 10 MHz and L-Band is a passive device designed to combine or separate 10 MHz reference signals and L-Band frequencies, making it ideal for applications involving Low Noise Block downconverters (LNBs) or Block Upconverters (BUCs).
Key Features:
- Low insertion loss for L-Band signals
- Outdoor-rated with IP67 ingress protection
- Wide operating temperature range from -40°C to +80°C
- Passive operation, requiring no external power
- Available with F-type, N-type, or SMA connectors

This diplexer is particularly useful when an external 10 MHz reference signal is required for devices like LNBs or BUCs. It can be paired with Swedish Microwave’s 10 MHz reference oscillator or other compatible signal sources. The device supports 22 kHz tone bypass through the receiver or an external source, though this feature is not available when DC blocking is applied to the input or output.
