Bias Driver and RF Power Considerations
The MASW-011098 includes integrated DC blocks and RF bias networks but requires external bias control. MACOM identifies the MADR-011020 as a compatible switch driver.
Under standard test conditions, a 20mA forward bias is applied to the selected switching path, while the other path is reverse-biased at −15V. Higher RF incident power may require a more negative reverse bias voltage.
For the specified 13W CW power condition, MACOM uses −25V reverse bias at 26.5GHz and +85°C. Designers should also evaluate impedance matching, thermal grounding and RF input power before integration.
Typical Applications
Ka-band 5G wireless infrastructure
Radar and point-to-point communication systems
RF test and measurement equipment
Millimeter-wave signal routing
High-frequency transmit/receive switching systems
FAQ
What is the maximum RF power of the MASW-011098?
MACOM specifies 13W CW power handling at 26.5GHz, +85°C and −25V reverse bias. This is a condition-specific specification, not a guaranteed rating at every frequency and bias condition.
Does the MASW-011098 require an external bias driver?
Yes. The switch requires external PIN diode bias control. The MACOM MADR-011020 is listed as a compatible driver. The control circuit must provide the required forward current and reverse bias voltage.
Is the MASW-011098 an absorptive or reflective RF switch?
The MASW-011098 is a reflective SPDT switch. The OFF-state RF path is not internally terminated to 50Ω. Designers should account for reflected RF power when selecting the switch for sensitive signal-routing applications.
