Looking for clean SS HF PA w/QSK - part 6 (Russian Burst-2000A)

Hi all,

Thanks to www.cqdx.ru we can see very first general specification of the new LDMOS HF PA which is rated at 2.2kW output thru all HF bands up to 50MHz:


As you know my preview parts talked about:
ACOM 1200S
LINEAR Amp Gemini HF-1K

Azden AZR-1000

Elecraft KPA1500

The Burst-2000A is using water cooling system and it is promising all possible protections which could be implemented.

An interesting think is the exciting power just 15W only to get full power of 2.2kW and full automatic switching system.

Unfortunately it looks like there is no ATU inside and mainly there is nothing said about the T/R system used in the amplifier. So we can doubt if this LDMOS PA has full, fast and silent QSK implemented.

So we will have to wait until more information will be published...
