Description
Alpha’s AV850M2-00 MMIC voltage variable attenuator
is a standard TEE configuration incorporating triple-gate
0.25
m power MESFETs. The attenuator has a typical
insertion loss of 3 dB over the 10–40 GHz band. The
attenuation range is 35 dB while typical I/P and O/P return
loss is better than 6 dB. 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 or solder die attach process.
This chip incorporates triple-gate FETs which results in less
attenuation variation over temperature as well as better power
handling performance at all attenuation states. All chips are
screened for insertion loss, full attenuation and I/P and O/P
match over the 10–43.5 GHz band for guaranteed
performance.
