High frequency projects completed by the NIKMA Engineering team
A bandpass filter for various ranges
A bandpass filter for various ranges from 1.8 to 30 MHz. The bands of the filters are switched with the help of a decoder, to the input of which comes the logical levels from the control device (transceiver, for example). The board is powered by 5V, the maximum current consumption is 35 mA. The logical unit level for range control can be used both TTL and CMOS (3.3V or 5V) for this purpose the board has a jumper. The filter's band attenuation is 1.3 dB. The bandwidth is determined by the range in which the filter is operating at the moment.
Controller for power amplifier control
Power supply voltage - 10-20V. The controller is designed to control the power amplifier during operation. It has measuring circuits of a supply voltage of the amplifier, its current, the level of the incident and reverse waves (on the basis of which it is possible to measure the standing wave ratio), temperature, has an input for connecting a temperature sensor for protection against overheating. At the output, it gives out a logic code of control of ranges of the LF filter of the amplifier. Has a PTT signal, can control the receiving/transmitting relay. The control buttons can be used both on the board and those that can be connected externally. The controller has an acoustic alarm, which will trigger either overheating, or if the standing wave ratio is bad, or if the power supply voltage is too high or if the current consumption is too high. If any of the protections are triggered, the amplifier connected to the controller will forcibly shut down and the acoustic alarm will not.
Switch for control of "receiving and transmitting" signals
Switch for control of "receiving and transmitting" signals with integrated low noise amplifier. Powered by 12-20V voltage. It has its own 5V 2A converter, which can be used for other needs of radio amateurs. On the board, there is a possibility of soldering the driver power amplifier. Switchboard can connect or disconnect the receiver's bandpass filter. The signal from the antenna can be amplified by the built-in low noise amplifier, if the signal is very powerful, it is possible to pass the amplifier on the pass with 0dB loss. The built-in amplifier is available in two versions (BFG135 transistors with 12 dB gain or GALI74+ assembly with 16dB gain). The transistor amplifier has a lower noise figure but also lower gain. It is possible to control either logic 0 or logic 1 and there is a jumper on the board for this purpose.
Radio Amplifier
An amateur radio amplifier operating in the frequency range 1.5 - 50MHz. The power supply voltage of the amplifier is 13.8 V, the output power is 10 W over the entire frequency range, and the gain is 50 dB. The maximum current consumption is 1.48 A, the quiescent current is 0.43 A. Frequency response in the entire frequency range is 3 dB.
