the microamp MB-15 circuit board is designed for rapid prototyping of actve frequency multpliers using hitte microwave devices in lp4e packages with rf inputs on pin 3, rf outputs on pin 16, and bias connectons on pins 19-23. multplier mmics are available in various multplicaton factors with output frequencies throughout the x and ku-band range. this board will ?t the microamp mh series of connectorized housings that allow it to be used as a stand-alone multplier or cascaded with other microamp boards for added versatlity. boards are fabricated from a high-performance 13 mil thick ro-4350 laminate with rohs compatble enig platng (electroless nickel/immersion gold) on both the component side and the solid botom ground plane. the board measures 0.490" x 0.590" and mounts into the housing with four or eight #1-72 screws for optmal high frequency grounding. multplier 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 afer it is installed into the housing, as well as a large pad to connect the bias voltage to a feed-through. check the speci?c data sheet for the multplier being used. many of the pins are unused and need not be soldered to the ground plane. assembly multiplier schematic for additional product information, plea s e visit www .twinind.com contact information: 925-866-8946 (phone) 925-866-8937 (fax) sales@twinind.com microamp MB-15 circuit board for hittite multipliers in lp4e packages ref size function c1 0402 bias bypass (not labeled) c2 0402 bias bypass (not labeled) c3 0402 bias bypass (not labeled) c4 0402 bias bypass (not labeled) c4 0603 bias bypass (not labeled) u1 lp4e multplier j1 rf input (pin 3) j2 rf output (pin 16) j3 + bias (pins 19-23) ? fits hitte microwave frequency multpliers with lp4e packages ? usable with hmc368, 370, 443-445, 575, 695 multpliers ? output frequencies in x and ku band ? uses standard smd passive parts ? ro-4350 board material ? fits microamp mh-series housings features
