rf attenuator parts named for an inquiry, not a stock list

How to separate a fixed pad from a lookalike part

A fixed coaxial barrel, a PCB resistor network, and a switched step box can share the words rf attenuator parts and still be different purchases. Write the mechanical form first. Then write attenuation as a number in dB, impedance as 50 ohm or 75 ohm, and average power with the temperature the rating uses. A 6 dB label without a tolerance is incomplete. Many datasheets print something like ±0.3 dB or ±0.5 dB inside a stated band. Copy the tolerance from the file you hold instead of borrowing a neighbor model.

Connector sex matters on a barrel. Male-to-female, female-to-female, and male-to-male change the adapters you still have to buy. Pin depth and coupling nut style belong on the drawing. A center pin that sits proud can damage the mating jack, so ask which gauge the plant uses. Frequency and power still have to come from that same drawing. An SMA body discussed to 18 GHz is not automatically a 40 GHz part. A 2 W average rating at 25 °C is a question for the offered model, not a default for every row on this page.

Open the SMA quote checklist when the interface is already SMA and you need watt, VSWR, and exclusion lines before a headline number is treated as landed cost. Quantity, destination, and timing go on the RFQ form. This catalog does not certify match, does not hold inventory, and does not turn a photo of a coupling nut into a power rating. If the name you need is absent, type it in the requirement text. The three labels above are inquiry options inside Antennas and RF Components, not a closed catalog of every pad that exists.
