Description
The MAMF-011015 is an 8 - 11 GHz multifunction
GaAs MMIC designed for communication radar and
weather applications. It functions in combination with
an advanced Si serial-controller which addresses the
GaAs chip for the necessary RX/TX selection path
and the required signal controls, along with several
other functionalities.
The MAMF-011015’s GaAs chip utilizes a 0.25 µm
pHEMT GaAs process which has been optimized for
RF power, low noise, and RF signal control
applications which is ideal for high levels of
integration on a single IC. This GaAs MMIC includes
a “Common path” circuit where it incorporates a
4-BIT digital attenuator, a 6-BIT digital phase shifter,
and a T/R SPDT switch for RX/TX selection. The “RX
path” incorporates a low noise amplifier and
2 additional higher attenuation bits. The “TX path”
driver amplifier is designed to deliver sufficient RF
power and gain for an outside power amplifier.

The MAMF-011015’s Si serial-controller chip is
designed to address the GaAs chip’s common path
signal control components along with several other
functionalities such as external G/D control enabling
or disabling internal gate/drain switching of the LNA
or driver amplifier. When internal gate switching is
disabled, external drain switching may be used for
fast T/R switching (pulsing).
