YL1050 and TH327 PAs also exhibit the same variations at 23cm and it is considered normal. Everyone should be aware of this fact before they get started. In fact, after testing over 20 tubes, It appears that only one of somewhere from 5 to 7 are good for 23cm, so testing GS-23b tubes for 23cm suitability is a necessity. If input circuit trimmers, need to be at maximum or minimum capacity during adjusting, it is necessary to change the length of the cable between the exciter and the amplifier itself. The optimal length of the cable should be determined experimentally to obtain adjustment with approximately the calculated values of capacitances. 23cM EME stations have all adapted a circular polarization standard. Thus polarization rotation becomes a nonissue. Virtually every successful 23cM EME station uses a parabolic surface and a feedhorn for its antenna. Because the circular polarity reverses upon reflection from the moon, the feedhorn must also be able to do this.

On 23cm, an amplifier using just one '286' can be driven into saturation with as little as 3 or 4 watts, and a pair with less than 10, making that last configuration a close match for many of the 10w radios in use today. With 8 to 10 watts drive, a pair of them will easily deliver 150 watts.Klitzing 23 cm Amplifier.

Like the W6PQL design, the PE1RKI (Bert Modderman) amp uses a pair of XRF-286 transistors, but comes fully assembled and tested AND worked out cheaper (Dec 2012) than stuffing around building your own.

Mar 18, 2012 · For a while I operated on 23cm with just my IC-910 with it’s UX-910 module, this was only 10w. Rather luckily John G4BAO lives local and had designed and published a nice 45w LDMOS 23cm amplifier. It was quite easy to go put a pair together using a pair of W6PQL hybrid combiners.

23cm module. You will notice on the left of the picture above, I have a 6dB SMA attenuator at the input, so I can safely drive the amplifier with a TS2000X (or any 23cm rig <=10W output). The blue cable you see is 50 ohm semi rigid cable, which is very low loss on 23cm. If input circuit trimmers, need to be at maximum or minimum capacity during adjusting, it is necessary to change the length of the cable between the exciter and the amplifier itself. The optimal length of the cable should be determined experimentally to obtain adjustment with approximately the calculated values of capacitances.
