Help Identifying Power Connectors on RF Amplifier

[canadaboy25]

Does anyone know what type of connectors this RF amplifier is using for the power input?

Is there an actual connector or are they just posts to wrap and solder wires to?

...or are they just posts to wrap and solder wires to?

Yup, just posts to wrap and solder a wire to... Though, the positive Vcc "post" looks like a feedthrough capacitor.

The Vcc post is either a feedthru capacitor or an LC filter in a similar package.

Yes, except that you don’t really wrap around them. They’re formally known as “turrets” and this is how you solder to them:

The Vcc post is either a feedthru capacitor or an LC filter in a similar package.

Or, as I suspect, just a plain old insulated terminal.

Here is what mini-circuits has to say on the subject covering both IPC-A-610 and NASA-STD 8739.3 :

NOTE: Published Assembly Standards present conflicting information regarding wire
wrapping around the terminal, e.g.
• Per IPC-A-610
1. Wrap wire larger than #30 AWG a minimum of 180° and a
maximum of 270°.
2. For # 30 AWG and smaller, wrap wire two times (720°) around
terminal post and a maximum of 3 times, wire does not overlap or
cross over itself on the terminal.
• Per NASA-STD 8739.3
1. Wrap wire larger than #26 AWG a minimum of 180° to a maximum
of 270°.
2. For #26 AWG and smaller, wrap wire a minimum of 180° but less
than 360
Mini-Circuits recommends following the IPC-A-610 Standard as this is the generally
accepted world-wide assembly standard for commercial applications.
