6 GHz RF Signal GeneratorPN: PWRMOD-001, Last updated: May 2024 (Rev A)![]() This module generates a 6.3 GHz signal from a local oscillator and outputs over an SMA connector. The device includes a compact, low-noise regulator for generating the main bus voltage and a dual-rail regulator for generating the amplifier gate voltages. The amplifier on the device is listed with a maximum frequency of 6 GHz, but the response curves in the datasheet indicate the component can work up to approximately 8 GHz. Consider adding one additional header on the VTUNE net for the VCO so that the generated frequency can be manually adjusted if needed. Major components include: |
