MAMF-011015 X-Band Multifunction MMIC Rev. V4 8 - 11 GHz Features Functional Schematic T Gain: 11 dB X T P : 23 dBm X SAT R Gain: 24 dB X R Noise Figure: 2 dB X Lead-Free 7 mm 44-Lead PQFN Package Halogen-Free Green Mold Compound RoHS* Compliant 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 R /T selection path X X and the required signal controls, along with several other functionalities. 2 Pin Configuration The MAMF-011015s GaAs chip utilizes a 0.25 m Pin Function Pin Function pHEMT GaAs process which has been optimized for 1 - 3 No Connection 25 V RF power, low noise, and RF signal control OPT2 applications which is ideal for high levels of 4 Ground 26 V LNA G integration on a single IC. This GaAs MMIC includes 5 Common 27 Ground a Common path circuit where it incorporates a 6 Ground 28 R IN 4-BIT digital attenuator, a 6-BIT digital phase shifter, 7 V 29 Ground EE and a T/R SPDT switch for R /T selection. The R X X X 8 Ground 30 V path incorporates a low noise amplifier and CC1 2 additional higher attenuation bits. The T path X 9 - 11 No Connection 31 Ground driver amplifier is designed to deliver sufficient RF 12 V 32 T OUT CC2 power and gain for an outside power amplifier. 13 SER IN 33 Ground 14 CLK 34 DET The MAMF-011015s Si serial-controller chip is 15 LE 35 REF designed to address the GaAs chips common path signal control components along with several other 16 RS 36 No Connection functionalities such as external G/D control enabling 17 TR 37 V DD2 or disabling internal gate/drain switching of the LNA 18 EN 38 V DD1 or driver amplifier. When internal gate switching is 19 No Connection 39 No Connection disabled, external drain switching may be used for 20 SWEN2 40 TEMP SENSE fast T/R switching (pulsing). 21 SER OUT 41 V PA12 G 22 V 42 No Connection 1 EE Ordering Information 23 SW2A50 43 G/D Part Number Package 24 SW2B50 44 No Connection 3 45 Ground MAMF-011015-TR0500 500 Piece Reel 2.
