FAQ
What is the operating frequency of the MASW-011249?
The MASW-011249 operates from 0.01GHz to 7GHz, equivalent to 10MHz to 7GHz.
Is the MASW-011249 rated for 200W or 240W?
MACOM describes the part as a 200W high-power switch. The datasheet shows up to 240W CW at 1.8GHz, +85°C case temperature and 200mA TX bias current. The achievable power depends on frequency, temperature, bias and system impedance.
What is the typical insertion loss?
Typical TX-path insertion loss is 0.20dB at 1.8GHz, increasing to 0.49dB at 6GHz. Typical RX-path insertion loss ranges from 0.20dB at 1.8GHz to 0.67dB at 6GHz.
Does the MASW-011249 contain an integrated driver?
No integrated digital driver is specified. The switch requires an external bias and control network capable of providing the required PIN diode current and reverse voltage.
Is an evaluation board available?
Yes. MACOM lists the MASW-011249-SMB sample board for device testing and design evaluation.
What package does it use?
The MASW-011249 is supplied in a lead-free 5mm 20-lead HQFN surface-mount package.
