Integration and Thermal Considerations
The AT-AM3-0918-15L is available in multiple configurations: standard module with external DC power supply or compact bench-top variant (PN-LCBT) featuring integrated AC/DC adapter. For sustained operation, thermal management becomes critical when case temperature approaches 50 °C; AT Microwave recommends auxiliary heatsinking or active cooling to ensure long-term reliability and output power stability.
Engineers selecting this multiplier benefit from minimal input drive requirements, broadband coverage, and straightforward SMA interconnectivity—reducing design complexity while preserving system performance.
