Shortwave Tuned Filter Amplifier with Transmit and Pass Modes, Frequency Coverage 3-30MHz, Adjustable Gain 0-30dB Description
This unit is a receiving amplifier with a shortwave tunable bandpass filter center frequency, covering a frequency range of 3-30MHz, and an adjustable gain of 0-30dB.
Signals from the ANT interface are filtered by the built-in shortwave tunable narrowband filter, amplified by a low-noise amplifier, and then sent to the RX/TX interface.
The bandwidth of the tunable narrowband filter is approximately 1MHz. Adjusting the filter knob to reach the target frequency allows the signal at that frequency to pass through, while other frequency signals either side are attenuated. The filtered signal is then amplified by the low-noise amplifier, whose gain is adjustable. Adjusting the gain to a suitable level based the strength of the received signal and the dynamic range of the device prevents receiver overload.
Built-in relay allows transmission even when powered off or connected to the PTT signal . Maximum withstand voltage is AC 440V/ 120V, maximum withstand current is 8A. Please use below the maximum withstand voltage and current.
For both transmission and reception, please turn off the amplifier before transmitting or connect the PTT signal to the amplifier to control the internal relay .
