1500 +W dual ldmos blf188 linear amplifier board v2.0
1500 W LINEAR DUAL LDMOS POWER AMPLIFIER. This board is designed for two LDMOS-FET's operating in a push-pull circuit.
Thermal tracking of bias is also provided on board. This is a populated board but without the active LDMOS devices. The board is supplied ready for your devices to be dropped in.These are very high power boards. The board has enough "headroom" to cover up most minor operating mistakes. The LDMOS devices with the "XR" are Extremely rugged devices!! The amplifiers have very good IMD since the devices are designed to loaf along at the designed power level. They are not pushed to the limit or to saturation!
I was asked a few questions by members so here is my added reply. Amps are made for 160-6m. Slight trade off to set the right balance in power/bandwidth so there is.About 10% drop on 6. As for duty cycle If the boards are mounted as needed on. A proper heat sink with a good sized copper heat spreader with 10mm thickness. And air is directed on fins as well on top of board to cool the magnetic I. Was able to run the amps for a long time. Cores are large and many thus an. Average rise of core temperature is also controlled As a result I have not.
