VLF-1800+ Frequently Asked Questions (FAQ)
-
Mini-Circuits recommends a 4-layer PCB with a solid ground plane, and a low-impedance path to the amplifier's ground pin. A good layout practice is to keep the input and output traces separate and as short as possible, and to use via stitching to connect the ground plane to the amplifier's ground pin.
-
The VLF-1800+ is a self-biased amplifier, but it's still important to ensure the correct voltage supply and current limiting. Mini-Circuits recommends using a voltage regulator to maintain a stable 12V supply, and a current limiting resistor to prevent over-current conditions.
-
The VLF-1800+ can handle up to +10 dBm of input power without damage. However, it's recommended to limit the input power to +5 dBm or less to ensure optimal performance and prevent compression.
-
Common causes of oscillation or instability include poor PCB layout, inadequate grounding, or incorrect biasing. To troubleshoot, check the PCB layout and grounding scheme, ensure the correct voltage supply and current limiting, and verify that the input and output impedances are matched correctly.
-
Yes, the VLF-1800+ can be used in a push-pull or differential configuration to improve performance and reduce even-order distortion. However, this requires careful attention to the PCB layout and impedance matching to ensure optimal performance.
