making a 1uh coil
I am looking for the air coil inductor between 1uH ~100uH with sustaining 2A and operating until 50MHz(SRF) for power amplifier with MRF136. For this case, I think the chip air coil inductor is not available so I need to purchase the big size wound coil inductor.
The picture is the product of FM power amplifier with MRF136 but the company did not provide vendor lists at all. 3 coil inductors with red color are shown below.

Could you please recommend any manufacturers ?
Any suggestions are welcome.
