Maxim Integrated provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using 50Ω transmission lines.
The DS1870E-010+T&R requires a 3.3V power supply and a bias voltage of 2.5V on the VBIAS pin. Ensure that the power supply is clean and well-regulated, and that the bias voltage is set correctly using a voltage divider or a dedicated voltage reference.
The DS1870E-010+T&R has an operating temperature range of -40°C to +125°C, but it's recommended to operate it within a temperature range of -20°C to +85°C for optimal performance and reliability.
To troubleshoot issues with the DS1870E-010+T&R, use a oscilloscope to measure the output signal and check for signs of oscillation or instability. Also, verify that the power supply and bias voltage are correct, and that the PCB layout is correct and well-designed.
Yes, the DS1870E-010+T&R can be used in a non-50Ω system, but it requires impedance matching to ensure optimal performance. Use a Smith chart or impedance matching software to design a matching network that matches the output impedance of the DS1870E-010+T&R to the system impedance.
