HT004A is a low-noise RF amplifier (car radio signal booster) with cascaded design, maintaining low noise figure while effectively boosting signal gain. Optimized for automotive environments, compact and easy to install, suitable for improving radio reception in weak signal or high interference environments. Mainly used to enhance car radio signal reception, especially suitable for vehicles with weak signal coverage, high interference or poor factory radio performance. It can also be used as a general-purpose low-noise RF amplifier for other test or reception scenarios requiring weak signal amplification in this frequency band.
Frequency range: 20 MHz–6 GHz (full band coverage) Gain: typical 35 dB Max output: +20 dBm (1 dB compression point) Operating voltage/current: 3.3–6 VDC / 150 mA RF interface: SMA female, 50 Ω
