Voltage-variable attenuators span 600 MHz to 4.0 GHz

Voltage-variable attenuators span 600 MHz to 4.0 GHz

The VFVA500 series of voltage-variable attenuators consists of six models spanning the frequency range of 600 MHz to 4.0 GHz and provides a minimum of 25-dB attenuation across a 0 to 5-V control range. The design is a multichip module (MCM) consisting of a monolithic quadrature hybrid, two highly matched silicon PIN diodes, and bias and decoupling components.

The control of all the critical RF components provides the user with a continuous attenuation profile at an extremely high degree of repeatability. The VFVA500 series is offered in an easy-to-use 3.2 x 4.9-mm MCM surface-mount package. (Contact sales for pricing — samples available now.)
