The MicroAmp MB-15 circuit board is designed for rapid prototyping of active frequency multipliers using Hittite Microwave devices

in LP4E packages with RF inputs on pin 3, RF outputs on pin 16, and bias connections on pins 19-23. Multiplier MMICs are available in

various multiplication factors with output frequencies throughout the X and Ku-band range. This board will fit the MicroAmp MH

series of connectorized housings that allow it to be used as a stand-alone multiplier 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 eight #1-72 screws for optimal high frequency grounding. Multiplier circuits can be

easily assembled with standard surface-mount passive components. The MB-15 includes provisions for DC bias bypassing. Pads for

the input/output RF 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 a feed-through. Check the specific data sheet for the multiplier being used. Many of

the pins are unused and need not be soldered to the ground plane.
