Description
Alpha’s AV850M1-00 MMIC voltage variable attenuator is
a balanced configuration incorporating Lange couplers at
input and output. The attenuator has a typical insertion loss
of 2.5 dB over the 18–40 GHz band with a worst-case
insertion loss of 3.5 dB across the full 18–50 GHz band.
The attenuation range is 35 dB over the full 18–50 GHz
band while typical I/P and O/P return loss is better than
13 dB for all attenuation states. The chip uses Alpha’s
proven 0.25 µm MESFET technology and is based upon
MBE layers and electron beam lithography for the highest
uniformity and repeatability. The MMICs employ surface
passivation to ensure a rugged, reliable part with
through-substrate via holes and gold-based backside
metallization to facilitate a conductive epoxy die attach
process. All chips are screened for insertion loss, full
attenuation and I/P and O/P match over the 18–50 GHz
band for guaranteed performance.
