The HP calibration set that I used had cheap SMD chip resistors (!)
inside, which behave nicely up to several hundred MHz. The overall
high frequency performance is determined by the layout and connections
which are critical.
The resistors drifted a lot as expected and were checked before every

I have bought some resistors of 0.1, 1.0, 10, 100, 1k, 10k & 100k Ohms.
These are in little boxes with 4 BNC connectors spaced 22 mm apart.

although I paid a *lot* less.
They are designed for use verifying the performance of LCR meters. I
