| Replacement for the PM9610 Prescaler for Philips PM6654 High precision Counter |

| SaabFAN:
Your schematic looks good, except for the terminators R9 and R10. The way you have connected them, you have formed a voltage-divider with R1, resulting in a much lower DC-Voltage at Pin 3 of the MMIC. You need to isolate the DC-Supply from the terminators by two additional DC Block-Capacitors (see attached picture) |

I will make test platine :) Thank You |

I'd put way more clearance between the HF traces and the ground pours. Say at least 2mm or so but there are online tools which can calculate the minimum clearance between a microstrip and ground pours. |

reworked platine |

I would also add Ground-Stitching Vias to the board to connect the top and bottom ground-plane. |
