thanks for the datasheet, unfortunatly it doesnt give a max current for the coil, the part i have says 8.5-9.25GHz it tunes to 8GHz @ 150mA however i dont know if this is acceptable for long term operation.
I know about the phasenoise performance for the synthesizers thats why im using a SPD rather than a PLL Chip along with a 100MHz low phasenoise reference.
Endwave actually swallowed Stellex as far as i know, stellex used to be WJ components , then WJ became stellex and then stellex got taken over by endwave.

They're equivalent to these Endwave parts, as far as I can tell:
The YTOs themselves are nice parts, but the popular synthesizer boards that
use them are noisy. The comparison frequency is relatively low (250 kHz),
causing a 90-dB in-band PN penalty. With a higher Fcomp you can do quite a
bit better.

Does anyone has a detailed datasheet of the stellex permanent magnet
YTOs that are commonly offered on ebay ? im especially interested in
the max current the coil can take without frying.
Im in the process of building a 32GHz Synthesizer and want to use one
of those YIGs to generate a 8GHz Signal that then will be multiplied to
16GHz and then to 32GHz ,im planing on using a SPD from metelics for
this task driven by a 100MHz Crystal oscillator, i know theres better
stuff around but im trying to utilize stuff in got in my drawer.
Anyway i need a datasheet for the YTO to be able to properly design the
loop filter and driver circuitry.
