General Description
The HMC-AUH249 is a GaAs MMIC HEMT Distributed
Driver Amplifier die which operates between DC and
35 GHz and provides a typical 3 dB bandwidth of
37 GHz. The amplifier provides 15 dB of gain and
+23 dBm of saturated output power while requiring
only 200 mA from a +5V supply. The HMC-AUH249
exhibits very good gain and phase ripple beyond
25 GHz and can output greater than 8V peak-to-
peak, making it ideal for use in broadband wireless,
fiber optic communication and test equipment
applications. The amplifier die occupies less than
4 mm2 which facilitates easy integration into Multi-
Chip-Modules (MCMs). The HMC-AUH249 requires
a bias-tee as well as off-chip blocking components
and bypass capacitors for the DC supply lines. Vgg1
adjusts the bias current for the device while Vgg2
adjusts the output gain.
