1.85mm Female Solderless Straight Microstrip Connector DC–67 GHz VST-CPM185F-03
P/N: VST-CPM185F-03
- For repeatable 50 ohm microstrip PCB launches
- Solderless mounting for faster installation and replacement
- Stable straight transition for precision microwave boards
- Well suited to evaluation and high-frequency test fixtures
- Supports upper microwave applications through 67 GHz
Engineering Note
VST-CPM185F-03 is a 1.85mm female solderless straight connector for 50 ohm microstrip launches. It covers DC–67 GHz with VSWR ≤ 1.35 and uses a compact two-hole mounting format for repeatable board attachment. This structure is intended for high-frequency microstrip transitions where controlled impedance, consistent contact geometry, and straightforward replacement on evaluation or test boards are required.
