Functional Diagram
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.
