Voltage-variable attenuators are fully integrated

Suited for a variety of applications, such as wireless base stations, remote radio heads, tower mounted amplifiers, and general-purpose attenuation, the VFVA series of voltage-controlled variable attenuators is optimized for a variety of bands: 600 to 900, 700 to 1,100, 1,500 to 2,200, 1,800 to 2,400, 2,000 to 3,000, and 3,000 to 4,000 MHz. The design consists of a silicon monolithic quadrature hybrid, two highly matched silicon PIN diodes, and all bias and decoupling structures, which provide an easy-to-use highly repeatable devices.

Housed in a 3.2 x 4.9-mm MCM package, the series also features an IIP3 of 45 dB typ and an operating voltage from 0 to 5 V with a 1.5-mA typ current drain for maximum attenuation. Additional specifications include a maximum insertion loss of 1.5 dB and an attenuation of 23 dB minimum at 5 V. (Call company for pricing available now.)
