QPC4043
5 - 3000 MHz, 75 Ohm, Closed Loop Voltage Controlled Attenuator
QPC4043 is a fully monolithic voltage-controlled attenuator (VCA) that provides over 25 dB of gain control range over a frequency range of 5 MHz to 3000 MHz. The QPC4043 employs a closed loop design that provides a more controlled attenuation response over frequency and temperature conditions. This attenuator is matched to 75 Ω over its control range and frequency with no external matching components required. The QPC4043 is available in a space saving 16-pin 3 x 3 mm Laminate (LGA) package with minimal external components.
