Three years ago I bought a used commercial 13cm Amplifier online.... 


After he arrived after a few weeks, I was curious to test him. 
A sweep test was carried out and lo and behold, despite the fact that a circulator for 2600 MHz is built in, the amplifier works best exactly in our amateur radio band segment ( between 2280 and 2470 MHz ). There was no end to the enthusiasm, why not when you get almost 40 watts of output with 0.1mW input   ( perfect for use with Adalm Pluto ). 
So enthusiastically, I bought a total of 26 used amplifiers, converted what was necessary ( SMA connectors, heat sinks ) and distributed them among the amateur radio people. 
Due to great interest I wanted to buy a few more, unfortunately I couldn't find anything anymore ( it was probably just a small series from a well-known South Korean manufacturer for some small project ). 
Hides also got two of them and was thrilled because they are also suitable for DVB-T ( with 3~4 Watt DVB-T output), but more amplifiers are needed, what now ?

Strengthened by very good amplifier properties, HiDes decided to copy this amplifier, added a few improvements  
( housing , SMA ,  two 2.4GHz circulator ) and so a new amplifier for 2300~2450MHz was created, which I can test and present here.
According to Hides, amplifiers will soon be available in Hides eBay shop and on HiDes website  ( 599euro ) . 
I think it's positive that after the DVB-T Receiver-transmitter ,  3LNC70  downconverter   and  BU500 UPconverter, Hides has again offered something for amateur radio operators on the market.

RF monitor output:                  SMA female     (  -32dB  opposite output port  )
Input max. power:                    1mW           (  100mW is damage power  )
Amplifier size:                           15cm  x  10.5cm  x  2.2cm
Output protected by circulator from oversized antennas VSWR 
Protected against incorrect voltage reversal


Amplifier typical CW bandwidth sweep from a few finished amplifiers....





DVB Signal at the PA output - shoulder distance   &   5.2 Watt         ( with transmitter HV320  )

and a few more results at 5~6W PA output with HV320 as DVB source.....



    Proposal for use....








===============================================================================================
....in future there will also be a version with higher input power (  for BU500 holder or other transmitter ) , 
power amplifier with 100mW input and at the output port above 30W     ( PA with 25dB gain ).
