1kW 1.8-30MHz 700W 50MHz HF POWER AMPLIFIER BOARD LDMOS BLF188XR BLF188
You will receive of ready-made module: board (installed BLF188XR). It looks as you see in the photo above. This board was created to enable the use of the latest LDMOS-FET's devices. With this board, can be used with different types of LDMOS transistors. BLF178, BLF178XR, BLF188, BLF188XR, BLF578, BLF578XR, MRF6VP11KH, MRFE6VP61K25HR6. This 1400 W extremely rugged LDMOS power transistor for broadcast and industrial applications in the HF to 600 MHz band. The BLF188XR and BLF188XRS are capable of withstanding a load mismatch corresponding to VSWR > 65:1. In a range from 2 to 30MHz (test signal CW) BLF188XR, Pout is 1270W. FEATURES of the module with LDMOS BLF188XR.
Model: PA Unit BLF188XR - ReV. Modes Supported : FM, CW, SSB and others. BIAS adjusted in accordance with temperature.
Vbias: 12V for keying the amplifier. Additional elements for AFC correction. With attenuator on PA input. The heat sink and a copper heat spreader (not supplied) have to be larger than 200mm x 140mm and proper fan cooling must be provided too. To do this, divide the Board into two parts at the specified line.
If you want to get 1000W Pout, you need very low input power, about 3-5W Pin. In this order, you need to be very carefully on first power on.On 160m, 80m, 40m, 30m, 12m, 10m can be Pout up to 1200W. On 50MHz can be Pout up to 700W. On 70MHz can be Pout up to 500W. To increase the gain at frequencies of 30-70 MHz is possible by changing the values of capacitors C21, C11, C48. A full technical documents with all instructions on CD (in parcel) is provided with the board. Pictures of ready LPF600 + PA Unit of the amplifier with.
