Passive, surface mount device requires no bias or control voltages
Richardson RFPD Inc. announced the availability and full design support capabilities for a series of temperature-variable chip attenuators from Aeroflex/Inmet.
The Powerfilm™ TCAF N05 Series operates from DC to 12 GHz and is designed to vary -.005 dB/dB/ºC to compensate for temperature-induced system gain variation without requiring a bias or control voltage. Offered in a surface mount package, these attenuators consist of laser-trimmed thick film resistor elements on an alumina ceramic substrate with a protective paint layer. They are available in various metallization styles and plating options.
The flat broadband performance of the new attenuators allows for the creation of automatic- and passive-link margin compensation on a wide variety of transmit and receive chain circuit applications.
According to Aeroflex/Inmet, additional key features of the TCAF N05 Series include:
