[RF Transistor Evaluation Boards: Core Platforms for Signal Acquisition and Processing]

ON Semiconductor offers multiple specialised solutions in RF transistor evaluation boards, most notably the ARRAYX series. This range is specifically optimised for signal acquisition and processing of silicon photomultiplier (SiPM) arrays. The ARRAYX-BOB6-64S evaluation board facilitates straightforward access to all standard pixel signals and individual fast output signals from the ARRAYJ-60035-64P (6mm 8x8 TSV array). This design enables researchers to conduct photodetection conversion experiments and array performance testing with ease, proving particularly suitable for scientific and industrial applications demanding high-precision photodetection.

The evaluation board's connection architecture demonstrates high specialisation. The terminal block features two Samtec 80-way connectors (type QSE-040-01-F-D-A), which perfectly match the Samtec QTE-040-03-F-D-A board-to-board connectors on the array. The keyed design of these connectors facilitates straightforward and reliable array orientation on the Board of Board (BOB), significantly reducing installation and commissioning complexity. For rapid signal output, the evaluation board routes all fast output signals (Fn) via matching connectors to header pins. These consist of four 50-way (25x2 rows) connectors with 2.54mm pitch (J3, J4, J5, and J6). Each of the four headers also features 10 pins connected to the common cathode (CM) and 8 non-connected (NC) pins, providing flexibility for prototyping and evaluation.

Signal processing capability represents another key highlight of the ARRAYX evaluation board. Two SMA connectors and balun transformers are equipped with 4-pin headers, allowing any fast signal to connect directly to the SMA interface or via the transformer using jumper wires. This design offers multiple options for high-frequency signal measurement and transmission matching. The summed output (anodes of pixels 1 to 64 connected together) is routed to jumper pins near the third SMA connector (SM), facilitating overall signal strength monitoring. Mechanically, the evaluation board features four 7mm holes on a 25mm grid, specifically designed for mounting the board onto optical breadboards, ensuring stability in experimental setups.

ON Semiconductor also offers the ARRAYX-BOB3-144P evaluation board, specifically designed for the ARRAYC-30035-144P (3mm 12x12 SiPM array). This evaluation board incorporates four Samtec 80-way connectors, routing all signals from the array through paired connectors to header pins, forming eight 50-way (25×2 rows) 2.54mm pitch connectors. Three SMA connectors and a Balun transformer with 4-pin headers permit direct connection of any signal to the SMA or via the transformer using jumper wires. Similar to the BOB6-64S, the board incorporates four 7mm mounting holes on a 25mm grid for straightforward integration into optical experimental platforms.
