• RF bypass and bias capacitors
• Dual bias resistors
• RF bias inductor
• RO-4350 board material
• Fits MicroAmp MH-series housings
The MicroAmp MB-3 circuit board is designed for rapid prototyping of many different RF MMIC amplifiers in SOT-143 4-pin
packages that use a common RF output and bias pin from manufacturers such as Avago (MSA), Mini-Circuits (VAM), and others. This
board will fit the MicroAmp MH series of connectorized housings that allow it to be used as a single amplifier stage or cascaded with
other MicroAmp boards for added versaꢀlity. Boards are fabricated from a high-performance 13 mil thick RO-4350 laminate with
RoHS compaꢀble ENIG plaꢀng (electroless nickel/immersion gold) on both the component side and the solid boꢁom ground plane.
The board measures 0.490" x 0.590" and mounts into the housing with four #1-72 screws. Amplifiers can be easily designed and
assembled with standard surface-mount passive components. It includes provisions for input and output DC blocking capacitors
(0603), RF and bias bypass capacitors (0603/0805), dual bias resistors for flexible thermal management (0805), and a RF bias induc-
tor (0805 or 0603). Pads for the RF connectors allow the SMA center pins to be easily soldered to the board aꢂer it is installed into
the housing, as well as a large pad to connect the completed board assembly to the bias feed-through.
