Exceptional Profile Repeatability and High Linearity Voltage Variable Attenuators

HOPKINTON, MA - Feb. 23, 2011 - Valpey Fisher Corporation (NASDAQ: VPF), Microwave Products Group introduces the VFVA500 series of Voltage Variable Attenuators. The product family 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 – 5V control range.

“Valpey Fisher is excited to announce our line of extraordinary voltage variable attenuators,” said Michael Ferrantino Jr., President and Chief Executive Officer of Valpey Fisher Corporation. “Our design approach to the VFVA500 series offers our customers a differentiated attenuation profile in an easy to implement solution,” said Lou LaGrandier, Technical Director of Valpey Fisher’s Microwave Products Group.

The design is a multi-chip module (MCM) which consists of a monolithic quadrature hybrid, two highly matched silicon PIN diodes, 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.
