The RF broadband preamplifier uses an NPN VHF transistor as an untuned broadband (0.5 to 30 MHz) RF amplifier. Input impedance is 50Ω, allowing usage for all receiver inputs, and the unit has a 600-Ω output to match virtually all RF input circuits. The preamp delivers 30 dB of gain at 10 MHz, with a noise factor below 1 dB. Power for the preamp can be obtained from a variety of sources. The assembly requires from 9 to 14 Vdc and draws 8 mA of current. This makes it ideal for use in battery-operated portable equipment.
