Qorvo QPC4043EVB-01 Evaluation Board, available now from Mouser, is a demonstration and development platform for the QPC4043 Closed Loop Voltage-Controlled Attenuator.
The QPC4043 offers over 25dB of gain control range across a frequency range of 5MHz to 3000MHz. It utilises a closed-loop design that delivers a more controlled attenuation response over frequency and temperature conditions. This device is matched to 75-Ohm over its control range and frequency with no external matching components required.
The Evaluation Board provides a pre-mounted QPC4043 VCA in a space-saving 3mm x 3mm laminate Land Grid Array package. It supplies an example application circuit, enabling rapid prototyping when included into existing designs.
