Note: This baby is a spare part. If you need a finished product, please contact us. This product is a kit. Without heat sink and sma connector.
NOTE : The high-frequency power amplifier must be connected to the nominal load before it is powered on (this shop's power amplifier products default 50 Euro), this is very important!
This power amplifier is an upgraded version of RF-AMP-250 It can be used in wireless power transmission projects, radio power expansion, and scientific experiments. Input 0.5-10W, output 110W (7MHz), 64W (14MHz)
Note: The default configuration is equipped with low-pass capacitors according to the frequency of 7MHz. We can configure low-pass of 7MHz and 14MHz. If you need low-pass of 14MHz, please be sure to contact us (7MHz and 14MHz low general-purpose mica capacitors are different Yes, be sure to leave us a message!)
Size: 14x8 (cm) Weight: 110g Since this baby is not a complete machine, it needs to be installed in the chassis, but everyone's chassis is different. The size and shape of the heat sink are also different, so it is not equipped with a heat sink. The heat sink is bigger, a simple way to judge: touch it with your hand, as long as you can't stand it if it is not hot for a short time. See the following table for details: Input and output test results at 7MHz:
14MHz input and output test table:
ps: There are two data in the output test, one is the power number of the big red dot test, and the other is the Vpp value of the Puyuan DS1102E test. This can be mutually verified (the two data are different, whichever is the big red dot) This baby shop owner performed a full power test for 30 minutes. A total of 5 groups were tested. The output power changed about 1W (compared to the initial power-on and 30 minutes test completion). The thermal stability was good, and there was no burnout or collapse . The baby at the last link on this page also performed 5 full power tests. It can be seen from the photos that this circuit layout is strictly in accordance with the axisymmetric wiring layout, and the copper ground ensures the stable operation of the system. test environment:
Red dot reading:
From the oscilloscope data, you can see the degree of harmonic suppression of the output signal, and it can completely transmit effectively.
