Description and Applications

M/A-COM Tech’s MA4VAT2004-1061T is an HMIC PIN diode variable attenuator which utilizes an integrated 90 degree 3dB hybrid with a pair of silicon PIN diodes to perform the required attenuation function as D.C. voltage (current) is applied.

This device operates from 0 to 1.66 Volts at 150mA typical control current for maximum attenuation. The user can add external biasing resistors to the bias ports for higher voltage requirements as required.

The MA4VAT2004-1061T variable attenuator is designed for AGC circuit applications requiring:

• Low Insertion Loss

• Low distortion through attenuation

• Large dynamic range for wide spread spectrum
