Functional Diagram
General Description
The HMC-AUH256 is a GaAs MMIC HEMT four stage
Driver Amplifier which covers the frequency range
of 17.5 to 40 GHz. The chip can easily be integrated
into Multi-Chip-Modules (MCMs) due to its small (1.93
mm2) size. The HMC-AUH256 offers 21 dB of gain
and +20 dBm output power at 1 dB compression from
a bias supply of +5V @ 295 mA. The HMC-AUH256
may also be used as a frequency doubler. Detail bias
condition to achieve doubler operation.
Vdd1 = Vdd2 = Vdd3 = Vdd4 = 5V, Idd1 + Idd2 + Idd3 + Idd4 = 295mA
