MB-11

MicroAmp MB-11 Circuit Board For Hittite SOT-23 Prescalers FEATURES • Fits Hittite 6-pin SOT-23 prescaler packages • Divide by 2/4/8 configurations • Input frequencies up to 8 GHz • DC blocks on input and output • RO-4350 board material • Fits MicroAmp MH-series housings The MicroAmp MB-11 circuit board is designed for rapid prototyping of Hittite Microwave 6-pin SOT-23 prescalers. HMC-43X prescalers are available in divide by 2/4/8 versions (HMC-432/433/434) which operate at input frequencies as high as 8 GHz. This board will fit the MicroAmp MH series of connectorized housings that allow it to be used as a single prescaler or cascaded with other MicroAmp boards for added versatility. Boards are fabricated from a high-performance 13 mil thick RO-4350 laminate with RoHS compatible ENIG plating (electroless nickel/immersion gold) on both the component side and the solid bottom ground plane. The board measures 0.490" x 0.590" and mounts into the housing with four or six #1-72 screws to insure optimal grounding for high frequency operation. Prescaler circuits can be easily assembled with standard surface-mount passive components. It includes provisions for input and output DC blocking capacitors and bias bypass capacitors. Pads for the RF input/output connectors allow the SMA center pins to be easily soldered to the board after it is installed into the housing, as well as a large pad to connect the bias voltage to the feed-through. These prescalers have a tendency to output broadband noise or oscillations when not driven with sufficient input power. Consult the Hittite data sheets for proper drive levels.
