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
