The MAMF-011015 is an 8 - 11 GHz multifunctionGaAs MMIC designed for communication radar andweather applications. It functions in combination withan advanced Si serial-controller which addresses theGaAs chip for the necessary RX/TX selection pathand the required signal controls, along with severalother functionalities.
The MAMF-011015’s GaAs chip utilizes a 0.25 umpHEMT GaAs process which has been optimized forRF power, low noise, and RF signal controlapplications which is ideal for high levels ofintegration on a single IC. This GaAs MMIC includesa “Common path” circuit where it incorporates a4-BIT digital attenuator, a 6-BIT digital phase shifter,and a T/R SPDT switch for RX/TX selection. The “RXpath” incorporates a low noise amplifier and2 additional higher attenuation bits. The “TX path”driver amplifier is designed to deliver sufficient RFpower and gain for an outside power amplifier.
The MAMF-011015’s Si serial-controller chip isdesigned to address the GaAs chip’s common pathsignal control components along with several otherfunctionalities such as external G/D control enablingor disabling internal gate/drain switching of the LNAor driver amplifier. When internal gate switching isdisabled, external drain switching may be used forfast T/R switching (pulsing).
