C-band Multifunction MMIC

The MAMF-011165 is a 5.4 to 5.9 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-011165 is optimized for RF power, low noise, and RF signal control applications and is ideal for high levels of integration on a single IC. This MMIC includes a “Common path” circuit where it incorporates a 6-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 the “Tx path” driver amplifier is designed to deliver sufficient RF power and gain for an outside power amplifier.

The MAMF-011165 integrates a serial-controller to simplify device operation. The controller has an external G/D (Gate/Drain) control, enabling or disabling 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).
